Looks for Range (1/11)

  1. I haven't heard anyone mention CFE-Pistol. It may not work as well for heavier bullets, but I get about 1400 fps from 155gr HP's out of my Sig-P220.
  2. Keep the 650, add MBF and RF100. That will save you tons of time, and both would work just as well with a 1050 if you ever do decide to go that way! Mike
  3. Does anybody know it Prima-V is temperature sensitive?
  4. Unless there was something preventing them from seating correctly the first time, with the normal amount of pressure! Mike
  5. I use an EGW U-die and never check anything, no push test, and no chamber gage. I never have a problem. If you get your setup right, checking is pretty much a waste of time. It may be worth the peace of mind for a major match, but no way for a local or practice. Mike
  6. 1% failure is unacceptable. If you have ammo that will go into the EGW gage and still not chamber, you may need to open up your chamber. I use an EGW u-die, but my gun has a Schuemann chambered barrel on it. I don't check anything, and never have a problem. Mike
  7. GlockGuru, did you join just to tell us that? Wouldn't be sponsored would you? Mike
  8. Yeah, but if you're a "C" class shooter, you're pretty happy with that! Mike
  9. Actually, I think you figured in 2 too many splits. With each 5 shots, you have 4 splits. I think a lot of people can get 5 shots off in under a second on targets this close, so that allows a little extra time on the draw and reload to stay around the 8 second mark. Mike
  10. I have shot this classifier twice in my relatively short career, and I seem to do better on this one than I average on most others. The last one I shot about a month ago I had 98 points in 8.04 seconds for a 73.25%. However, I think it would take a ton of improvement for me to do better on it than that! Mike
  11. You will never get enough of either one in a pistol case to even come close to making major! Mike
  12. HANDGUN PRIMER THOUGHTS & RECOMMENDATIONS FROM THE PROS One of the more difficult choices we make is deciding which primer to use. Are they all the same? When should I use magnum primers? Wouldn't magnum primers be better for everything? If you load for a Magnum-named cartridge (i.e. .357, .44 etc) should you always use a magnum primer? Do certain powders need certain primers? While not a definitive chart, the opinions presented below will hopefully answer a few of those questions for you and make your choices easier. It has been brought out by Dave Scovill, editor of Handloader magazine, and one of its earlier contributors, the late Bob Hagel, that certain primers work well better with certain powders. Hagel did a large body of research on this subject in 1982, and Scovill has done some follow-up checking and research. In addition, Brian Pearce has done a lot of work with handguns and has some opinions that collaborate what the other two have found in their research. Hagel's 1982 article is available online at this link: "Primers for Magnum Handguns". Info by Scovill and Pearce is found in the October and December 2011 issues of Handloader magazine. Some trends were noticed: Large Pistol Primers: Federal 150 were as good as any, and better in some instances. Scovill reports that for all practical purposes, they are the best choice for general applications in .44- and .45-caliber non-magnum loads. Hagel observes: “...[standard] primers made by Federal... in both Large and Small Pistol sizes for many years are not surpassed in any form of performance with any bullet weight with most powders in the .41 and .44 Magnum cases, by the... 155 magnum primer or in .357 Magnum by the 200 magnum primer pistol primer.” Winchester WLP is fine with faster-burning powders. CCI 350 - From Scovill’s experiments he concluded the CCI 350 Magnum primer has no value over its non-magnum 300 counterpart, with the exception of use with IMR-4227 in loads that do not exceed 20,000 psi in the .45 Colt. Remington 2 ½ are excellent with all the cartridges and bullets weights tested (.41 & .44 Mag). Small Pistol Primers: CCI 500 is more than adequate for faster powders at traditional .38 Special pressures. The CCI 500 primer and Titegroup are an outstanding combination in the .38 Special/158-gr. CCI 550 Magnum primers were developed in response to the availability of Winchester Ball powders 231 and especially 296. Federal 200 - Hagel: “After working with this primer and 2400 quite extensively, I concluded that it should not be used with that powder in the .357 Magnum. Pearce: "...the .327 Federal Magnum is loaded to around 45,000 psi, some 10,000 psi greater than the .357 Magnum... In this application, at least with full-power loads, a primer designed to withstand that much pressure without deformation should be selected. A good example is the Federal 200, the same primer that the factory uses." Remington 1 ½ are excellent with all the cartridges and bullets weights tested (.357 Mag). The use of magnum primers in some instances appears to generate higher pressures without the attendant - expected - increase in velocity. Magnum pistol primers except CCI’s show no superiority over those assumed to be of standard power when used to ignite slow-burning powders of any type, including spherical, and often give less velocity and uniformity. According to Pearce: “In magnum revolver cartridges, such as the .357, .41 and .44, the powder should be determined before selecting a primer. This is important, as many magnum revolver cartridge powders perform better when ignited with a Standard primer rather than a Magnum primer. This has been proven in several ballistic labs, not to mention my own testing and experience. In one lab test, .44 Magnum loads containing 2400 increased 11,000 psi when capped with a CCI 350 magnum primer versus the same charge capped with a CCI 300 standard primer. As a result, the powder charge must be reduced to stay within SAAMI pressure guidelines, which likewise reduces velocity." Sometimes this slips by the reloading manual people. A good example is the 1994 #12 Speer manual where CCI magnum primers were used in 2400 data. When Pearce told Speer's Allan Jones about this, at first he was skeptical. Then he re-shot the 2400 data using standard primers and confirmed Pearce's claim was correct. The data was corrected in the #13 manual with the significantly better performance of the standard primer published. Oddly enough there is an anomaly with Accurate #9 (that was used as an OEM .357 and .44 Mag powder by a major ammunition company dating back to the 1970s with standard primers) according to Pearce. When Western Powders bought Accurate Arms, they posted data shot with a magnum primer - which contradicted what Accurate had always said. Western's ballistician, Keith Anderson recognizes that AA #9 is best served with standard primers, resulting in lower extreme spreads, better accuracy and greater velocity. However the reason Western began using magnum primers was the powder charges were greater with standard primers, and they felt that the average guy would purchase magnum primers for his magnum revolver, then use published data that was developed with standard primers. The result would be high-pressure loads. So, figuring on the worst-case scenario, the company chose to use magnum primers with its data. That doesn't mean YOU should, because now you know better! Your powder charge can be a bit higher as well. Standard primers are needed for best performance when using the following magnum revolver powders: Alliant 2400 Accurate #9 Alliant Power Pro 300-MP Vihtavuori N110 This is in accordance with recommendations from both Alliant and Accurate/Western Powder. Magnum primers are strongly suggested to obtain reliable ignition under all conditions and with a wide range of bullet weights when using the following magnum revolver powders: Hodgdon H-110 Winchester 296 Hodgdon Lil’Gun With these powders standard weight bullets will generally ignite reliably with standard primers in warm temperatures. However, when the mercury plummets, ignition issues can be a real and potentially dangerous problem. In subzero temperatures, Brian Pearce has seen bullets from full-power .44 Magnum loads exit the barrel at about the same speed as he can throw a rock! When matched with light-for-caliber bullets, magnum primers become even more important to obtain reliable and consistent powder ignition. Heavy-for-caliber bullets tend to help this powder burn more uniformly, and standard primers can often give excellent results, but cold weather ignition issues can still arise. So magnum primers are still suggested. « Last Edit: November 12, 2011, 10:10:56 AM by Frisco Pete »
  13. .45 ACP BRASS WITH SMALL PRIMER POCKETS?? Quote Would the owners of Federal and Blazer please stop by the house so we can have a chat. Just why in the he!! do you have to make some with small primers????? Nothing I hate more when reloading and have some mixed in with normal brass. Anyone know why they do this? I understand with x39 brass its made in 50 different countries so there is going to be some variances, but this is .45ACP. As you can see from the above post, there is a problem that has cropped up lately for .45 ACP reloaders that somewhat fits in the Primer Info - Chart & Milspec Primers for Semi-Autos FAQ category. While Large Pistol primers were standard in .45 ACP for nearly 100 years, lately some brass comes with Small Pistol primers/pockets, or sometimes enlarged flash holes. How does this affect the reloader and why is this so? Here's some info on the subject gleaned from an article in the Oct 2011 HANDLOADER magazine by Charles E. Petty entitled "HOW GREEN IS MY PRIMER": He starts off with a nice little quote that applies: "beware of zealots of any stripe" because a good thing can be taken too far - as it is with these non-toxic primers. That is the reason behind the change in some instances to small pistol primers - to work with Lead-Free or Non-Toxic primers. With lead-free *DDNP primer compounds is that the initial primer pressure impulse is greater than normal primers, and there have been reports of damage to the breech face of a gun due to that temporary primer set-back factor. Correction has taken two paths: 1: Reduce the amount of mix (small primers) or 2: Reduce the initial pressure (with larger flash holes) In addition, you will see that some primers are actually crimped into the case to prevent set-back. Do either of these changes require an adjustment in current .45 ACP loads? In my [Charles Petty] test loads with powders commonly used in the .45 ACP, cases with the larger flash hole gave the same velocity and accuracy as loads in standard cases. Nor did the substitution of a small pistol primer seem to make any difference. It was uneventful. Should brass with the small primer pocket get mixed with the normal brass and you try to shove a large primer in, things are going to come to an abrupt halt - especially on progressive presses. Identification of lead-free or conventional primers is rarely a problem, because manufacturers mark boxes, cases, or the primers themselves to indicate the difference. Remington stamps a small LF on the primer. Federal stamps NT on the case. Winchester - some Super Clean ammo uses a blue primer sealer instead of the typical red color. CCI - New Blazer brass has a small primer. It is not marked as non-toxic. A call to the folks at CCI revealed that after their experience with the lead-free primers, they began to investigate small pistol primers in other .45 ACP loads. They found that the small pistol primer actually gave a slight improvement in consistency, but it also eliminated the need to inventory as much brass with a large primer pocket and, therefore, a significant cost saving. Not all their .45 ACP ammunition has changed, for Gold Dot, and Lawman loads continue to have the normal primer. The ammunition industry is a great example of economies of scale. Even if they only save a fraction of a penny per round, when you multiply by millions, it's real money. It is also obvious that they are not making or selling brass/ammo with the ease or simplicity of your future reloading in mind. So I guess we will now have to examine our .45 ACP brass more carefully from now on, especially range pickups, and segregate it by primer sizes. We still have the option to buy bulk brass like Starline or other brands from places like Midway etc. Some enterprising reloader may do well by "taking off your hands" all of your small pistol-primer-pocket .45 brass so he has a bunch of free or cheap brass that others don't want and he can set up for. *DDNP = diazodinitrophenol - as opposed to the standard lead styphnate compound in normal non-corrosive primers. « Last Edit: November 08, 2011, 09:49:53 AM by Frisco Pete » Logged "Board members turn feral in 24 hours or less - that's why we have Mods" - ranger1968 paraphrased.

  14. MILSPEC PRIMERS FOR SEMI-AUTOS FAQ AND INFO THERE IS A RE-OCCURING QUESTION AS TO WHICH PRIMER TO USE FOR RELOADING THE SKS, AK, AND OTHER MILITARY SEMI-AUTOS WITH FREE-FLOATING FIRING PINS. THE FOLLOWING HAS BEEN REPRODUCED AS A SAFETY GUIDE. Some rifles are much more susceptible to slam-fires than others. The SKS/AK are more susceptible than the AR15 and M1 Garand and M1A/M14, for example. Therefore, there is more 'forgiveness' built in to them as to primer selection. Another factor is rifle condition, parts tolerances, and cleanliness. A clean in-spec rifle is much more tolerant than one that isn't. While one, with luck, may shoot a lifetime with standard commercial primers and a free-floating FP - IT IS STRONGLY RECOMMENDED THAT YOU HEED THE ADVICE OF EXPERTS IN CHOOSING YOUR PRIMERS AND THEN SEAT THEM PROPERLY BELOW THE SURFACE OF THE CASE BASE. Another possibility is to have a MURRAY'S GUNSMITHING www.murraysguns.com spring-loaded firing pin installed in your SKS. This frees up your primer and ammunition choices. The SPEER reloading manual is an excellent source of expert advice and states the following: A slam-fire is the discharging of a cartridge in a firearm by the closing of the bolt without a pull of the trigger. In most cases this is a phenomenon associated with military-style semi-automatic rifles and handloaded ammunition. The slam-fire can be caused by a high primer or by a heavy, unsprung firing pin. High primers contribute to slam-fires because the closing bolt drives the high primer cup against the anvil. All handloads must be checked for high primers; this caution is even more important when shooting military-style semi-auto rifles. Slam-fires have been reported even when primers were properly seated. Many semi-auto service rifles have no firing pin spring and the firing pin itself is quite heavy. The inertia of the firing pin may cause it to snap forward as the bolt stops, firing the cartridge. If the bolt is not yet fully locked, the result can be a ruptured case with the potential for gun damage and injury to the shooter. Military primers are less sensitive than commercial primers to minimize this hazard. In 1994, CCI introduced the No. 34 [large rifle] and No. 41 [small rifle] primers for military semi-auto rifles... No. 34 primers are recommended for reloading 7.62mm NATO, 30-06 and 7.62x39 ammo for military semi-auto firearms. No. 34 and No. 41 primers feature mil-spec sensitivity to minimize slam-fires. They are both fully DOD-qualified primers for use in U.S. military ammunition. However, no primer can provide 100% protection against slam-fires if the loader doesn't seat the primers deeply enough, or the rifle has a headspace problem or an out-of-spec firing pin. PETER G. KOKALIS, noted military firearm author and expert, especially on select fire weapons, former Special Forces operator and combat veteran stated in the "Fighting Firearms" article on "Kalashniklones" the following: I have fired tens of thousands of rounds through several hundred Kalashnikovs of every make and configuration [and one can assume extensive SKS experience as well]... Military issue Kalashnikovs and their semi-auto equivalents [and the SKS] do not have spring-loaded firing pins. If commercial or reloaded ammunition - usually with primers more sensitive than milspec because of a thinner cup and sometimes a difference in the primer mixture - is fired in rifles of this type, the free-floating firing pin can, and eventually will, result in a slam fire with ignition out of battery. The resulting detonation can lead to self-destruction of the firearm and anatomical damage of varying severity to the shooter... [going on to speak of the then-loaded Black Hills 7.62x39 ammo] Aware of this primer-sensitivity problem, Black Hills is using the CCI No. 34 milspec primer... CMP U.S. RIFLE, CALIBER .30, M1 MANUAL Manual delivered with a CMP Garand, Ammunition section paragraph 3: ...In most military semi-automatic rifles including the M1, the firing pin will lightly mark ("dimple") the primer of a cartridge as it is chambered when the bolt closes. Military ammunition has harder (less sensitive) primers than are usually found in commercial ammunition or available to handloaders [the CCI #34 excepted], and such dimpling is normally insufficient to fire a primer provided the receiver, bolt, firing pin and chamber conform to prescribed design dimensions. However, the use of non-military ammuntion with softer (more sensitive) primers reduces the margin of safety and requires the shooter to exercise greater caution. Conditions arising from excessive wear, out-of-specification parts or heavy chamber fouling that might pose no hazard with military cartridges could be dangerous with other ammunition. RELOADING FOR THE M1 GARAND by KEN MARSH www.charm.net/~kmarsh/m1reload.html 3. Use a CCI mil-spec primer. These use primer cups that are harder than standard and help prevent slam-fires. Very important and often overlooked. Avoid high primers, which cause slam-fires. Store ammo nose-down and look across the case heads, that allows you to quickly inspect 50 or more cartridges at once. Also run your fingertip over all primers as they come out of the press or priming tool. RELOADING for the MATCH M14 by Glen D. Zediker www.zediker.com/downloads/14_loading.pdf Loading bench slam fire cures are primarily primers. First is choice. LC ammunition has a tough primer. The only commercially available primer I know of that’s similar in construction is the tough skinned WW®. CCI® is hard aplenty too. There is greater insurance against a slam fire using either of these primers. The one that, I say (as well as did every single gunsmith I’ve asked) not to use is Federal ®. It’s “touchier.” Remington® is okay, but not a positive step (in this direction). That’s too bad because the Federal® can work well with other .308 W. loads. Honestly, it’s a risk on an M14. Primers recommended for use in .308 Win/7.62x51/7.62x39 semiautomatic rifle loads: CCI #34, 200, BR2, CCI 250 Winchester WLR, WLRM Wolf LR ########################################################################################## SMALL RIFLE (.223/5.56) PRIMERS? The .223 Remington or 5.56mm NATO round is commonly found in semiautomatic rifles and also has special primer considerations using Small Rifle-size primers. Some recommendations follow: Primers used for .223 Rem. loads should have heavy cups to resist perforation at the high pressures normal for this round. Military 5.56mm primers have a cup thickness of about 0.24", compared to .020" or so that was traditional for the standard small rifle primers. Federal 205, 205M, Remington 7 1/2 BR, Winchester WSR, and CCI BR4, 450, #41, and Wolf SRM (QQQSRM) primers have cups of about the same thickness as military primers, and are the best to use when reloading the .223. The Remington 6 1/2 and 7 1/2 are essentially the same. The 7 1/2 cup metal is thicker so that the primer can stand up to higher pressures... cup thickness is 25 percent greater... BRIAN PEARCE (quoting Remington), Pg. 14, HANDLOADER, October 2006. The Remington 7 1/2 BR primer was developed for the hot, high-pressure 4100 fps. .17 Remington round and also used in .223 loads. When Freedom Arms transitioned the .454 Casull case to use the small primer, they picked the Rem. 7 1/2 BR because it gave reliable ignition and easily withstood the 65,000 psi generated by the hot pistol round. It is highly recommended for .223 AR15-type loads. CCI states: "The CCI 400 primer does have a thinner cup bottom than CCI 450, #41 or BR4 primers. The appropriate primer for an AR15 platform is the CCI #41 primer, which helps to prevent slamfires. With this primer there is more 'distance' between the tip of the anvil and the bottom of the cup." [as per: Linda Olin - CCI/Speer Technical Services]. Despite this, it seems that most AR15 reloaders have experienced no problems using the BR4 and 450 thicker cupped primers in rifles in good condition. The #41 gives the greatest safety margin however. The experts at 6mmBR.com have this to say about AR15 primer choice: For use in semi-automatics and AR15s, we advise that you stick to CCI and Remington primers. These brands have harder cups and are much less likely to pierce primers. Also, the AR15 has a free-floating firing pin that dents the primer on loading. This creates a risk of slam fires. So you want hard primer cups. The latest generation of Winchester primers, with brass-colored cups, should be avoided for AR15 use. The old silver Winchester primers worked fine, but the current WSRs are soft and can be pierced more easily than CCI or Rem primers. A poll of Highpower competitors (mostly shooting ARs) showed that Rem 7 1/2 primers are the most popular (33.23%), followed by CCIs (25.78%). The majority of CCI users favored the CCI BR4s, but both CCI 400s (small rifle standard) and CCI 450s (small rifle magnum) were also popular. Only 10.25% of Highpower shooters polled used Federal primers (either 205M or 205). At the time of the poll, many shooters reported using WSRs, but this was the older version with silver cups. Wolf also makes two small rifle primers that are suitable for 5.56 loading. First is their Small Rifle Magnum SRM primer (not the Standard). They have this to say: "If you are loading for an AR15 or Military Style semi auto rifle, or are loading high pressure cartridges in any other type of rifle ,we recommend you use the Magnum Small rifle primers. Both primers use the same amount of compound. The only difference is in the cup hardness. The WOLF Standard Small Rifle Primers have an all COPPER CUP, which is a little more sensitive than the brass cup magnum primers." Second is their newer Wolf Small Rifle 223 SR223 "This is the newest primer available in the Wolf line. It is ever so slightly hotter than the small rifle magnum primer and it comes with a brass colored thick cup. This primer can be used in place of the SRM primer or used when a different powder is used that is hard to ignite." There is no mention, as far as I can find, about how hard their Large Rifle primers are. Primers recommended for use in .223 Rem/5.56 semiautomatic rifle loads: CCI #41, 450, BR4 Federal 205, 205M Remington 7 1/2 BR Winchester WSR Wolf SRM Wolf SR223 PRIMER SEATING DEPTH AIDS Uniforming primer pockets about guarantees no primer sitting flush with or above the plane of the case head, which won’t guarantee no chance of a slam fire, but it won’t hurt. A uniformed pocket is assurance of consistent and adequate depth to get the primer the necessary 0.004 or more under the plane of the case head (0.008 isn’t too much). Use a primer pocket uniforming tool in place of a primer pocket cleaner. Next step is making sure they’re under the head. Run a finger across them; don’t just look. Primers have a beveled edge so can look (around the edges) like they’re seated below flush when the center of the primer is not. Believe it or not, your finger is extremely sensitive and accurate for feeling that the primer is below flush and is as accurate as a mechanical measure for the issue. If proper primer seating depth is an issue with the batch of cases that you are using, SINCLAIR INTERNATIONAL carries Primer Pocket Uniformers that can be chucked in a drill and used to uniform the primer pocket to a standard SAAMI depth and flat bottom for optimum primer seating or match prepping cases. I personally use them and consider these tough carbide-steel tools to be one of the better gadgets on my reloading bench. www.sinclairintl.com/product/11248/Primer-Pocket-Tools Large Primer 8000 Uniformer - Item UN-8002 Small Primer 8000 Uniformer - Item UN-8001 « Last Edit: November 10, 2011, 06:04:52 PM by Frisco Pete » Logged "Board members turn feral in 24 hours or less - that's why we have Mods" - ranger1968 paraphrased.

Federal 205 - Mil-Spec cup thickness according to Federal - okay for 5.56mm. .0225" cup thickness. Federal 205M - same as the 205 but the match version. Magtech PR-SR - .025" cup thickness (not much feedback yet on this new primer as to AR15 suitability but with the same cup thickness as the Rem 7 1/2 it looks good so far) Remington 6 ½ - thin .020" cup, intended for older, lower pressure rounds Remington says do not use for the .223 Rem or other similar pressure rounds. Good for .22 Hornet, .30 Carbine. Remington 7 ½ BR - A match or "bench rest" primer. Lyman & Nosler classify this primer as a Standard. Remington says the compound is the same as the 6 1/2 but with a thicker .025" cup. RWS 4033 Winchester WSR - some piercing issues noted when changed from silver to brass cup. Cup thickness is a bit thinner at .021". Most say they are good to go for the AR15 despite that, probably because of the hardness of the cup. Some feel they are less resistant to higher pressures. Wolf Small Rifle SR - soft, sensitive copper cup, not recommended for AR15/military rifle use or high pressure rounds. Small Rifle Magnum CCI 450 - same thicker .025" cup as the BR4 and #41. CCI #41 - commercial version of the fully-qualified DOD primer for use in U.S. military ammo. With this primer there is more 'distance' between the tip of the anvil and the bottom of the cup than with other CCI SR primers. .025" thick cup. Same primer mix as CCI 450.
