KKM 5,4" threaded. Seems to be the only decent quality threaded bull barrel easily available nowadays

When we talk about BARE slide, nothing over 10oz for me, please. If you ask me, all weight you take off makes the gun easier to shoot. Naturally, you must have some kind of dot tracking ability - for open novices it might be easier to shoot full mass slide (I think STI Trubor 5" is around 11.7 oz) at first and lighten the slide when the shooter has gained some experience. About Chirs´s video... To me it seems that the gun is recoiling pretty heavily back and forth, but of course it is hard to say from a vid. Can be because of 3N37 too.

What do you do, when shooting feels too easy ? Just remove rear sight blade and it gets alot more difficult: "...rear sight blade is just slowing my slide cycle..." I am kidding, right ? No, it was CHA-LEE today in Weld County match - what a great attitude

You mean 1911 single stack racegun ? Rick´s SS guns are awesome http://www.rickhebert.com/

Just noticed "GM" after your name in todays match results I am just slow as usual... Anyway: Congrats !!

9mm and non-ramped barrel... ? Go get decent quality ramped barrel and let your gunsmith machine the frame for it + fit the barrel. Load to 1.17" and test again. Loading longer does not always help however, if 1.17" does not work you could try (for example) 1.10" or even shorter and test again. If your gun has non-ramped barrel, you may need to do some mag tuning to make it work reliably. You should also note, it is a whole different thing to feed straight walled .40 than strongly tapered 9mm. Both have their own little things how to make them feed reliable. Like G-man said, in general how far backwards bottom of the ramp extends has alot to do with feeding. Just make sure your magazines and ramp does not meet each other... Wife´s 9mm single stack has fed all we have been feeding it with - so far shoots best groups with Zero 125gr JHP that looks pretty blunt nosed to me.

Yeah I know... I just was not very happy to wait 9 months to get decent barrel - maybe decent I know maybe 10-15 guys who have had same problems, keyholing or other problems with pretty low round count (less than 15k). I think even 9mm Major barrel should last at least 30k, but that is just me Problem seems to be, rifling gets beaten up cause it is very rough - "small caliber" expands and bullets do not get rotational speed they need. Obviously there are lots of good quality Schuemann barrels, I had .40 AET years ago and it was super nice - that was why I wanted to get more Schuemanns. But if there is any poor quality stuff around, I am gonna get it for sure Nowlin seems to make ramped 3.5" barrel... Thanks for the tip !

G-man, that barrel is Open 9mm 5.4" with regular 16" twist. There is a photo attached about .45 AET barrel I waited for 4.5 months - yes they were willing to change it, after another waiting period... I wanted to shoot that gun last summer and nobody else offered kind of barrel I wanted so I just lapped and installed it. Could not hone it even near to the point when drilling marks would have disappeared That gun does not get many rounds through it, I am just suffering but not gonna make the same mistake again. So what is the problem in real life ? There are 2 main problems : that .45 ACP barrel collects way more copper than my .223 Rem. and .204 Ruger barrels together. Other problem, I already shot out one of those barrels - bullets started to keyhole when it had 8600 rounds through it (9mm AET). My 5.4" 16" twist 9mm barrel seems to do little netter (probably because of wider rifles), but after 8000 rounds accuracy has decreased noticeably Just my 2 cents Have not found Officer barrel yet

Best barrels definitely work for me, but recent Schuemann´s are waaaay from that... I have got 2 crappy Schuemanns within a year and do not want to waste my money anymore. Cutting longer barrel down just does not work really good

Planning to build 1911 Officer´s ACP. Other parts seem to be pretty easy to get, but the barrel. Yes I know Schuemann makes them but not gonna buy that crap anymore - 2 pcs is enough for me. .45 ACP ramped W/N or P/C and gunsmith barrel non-drop-in, any ideas ?

If you only load your brass 5 times, you probably have pretty loose chamber and expanded brass will work usually. I prefer 10+ reloads, recent training brass has been loaded 17 times. Also when you have tighter chamber, reloading becomes 16x easier

To put is short : forget .38 Super rimmed, go with .38 Super Comp / .38 TJ.

Contact Steyr Mannlicher GmbH / Martin Fehringer, he should be able to get parts for you. If he is still working for Steyr... There has been lots of people moving in and out recently, seems there are nobody anymore that would really know these things I have SSG69 too, old one from 1992. Maybe 3rd trigger guard and 4th barrel.

2 possible reasons, pick your favourite : overtravel too tight or the rifle was charged with safety on. Have seen those things happening maybe 20 times, operator or lower receiver builder failure.

I guess I started the whole "reverse hydraulic dampening" hype in Finland years ago, so I may need to tell some experiences... Please note, it will also balance your rifle as Enidine weighs pretty much. Good with Skeleton stock and 18-20" Hbar barrel, but definitely not a good thing with .650" 16" barrel. Hydraulic dampening holds bolt/carrier/buffer combo back againts bottom of buffer tube little bit longer. It enhances rifle reliability with very light carrier/buffer setups when crappy mags are used or something similar is happening - magazine has more time to lift top round up, which was clearly visible when we shot some high-speed photos about AR-15 cycling. For some reason, it also prevents bolt bounce when full mass bolt carrier but lighweight buffer are used together. It also affects recoil pretty lot, which has advantages and disadvantages. When shooting off from bipod / prone, it does not feel good. However, my offhand shooting meters is slightly faster with hydraulic dampening when you have to aim. Have not tested it with new lightweight 6.7 oz setup yet, though. Close range I shoot anyway as fast as my trigger finger works (usually around 0.10-0.12 splits). I do not care about if recoil is soft or not, all what I care how fast my dot becomes back to target if it left it - clear difference between midlength and rifle gas systems with 16" barrels.

9mm mags are very often the reason for ejection failures. Does failures to eject appear when mag is full, almost empty or randomly ? Other 2 very common things are ejector itself and extractor. Does your ejector have pin that locks it in ? If not, install it first. Extractor should have .02" max travel, no more. For example, if you have 9mm Aftec and 9mm breech face = fail. One big thing is pistol timing. I would assume it is ok from DP but it is easy to check too. In 9mm brass is very important. Use only brass shot in that gun. For example, Glock brass will often cause problems and there is no way you could resize G brass to work in 9mm Opengun. I only put slide glide to upper and lower lugs, oil all other places. I do not like to use slide glide in slide rails, if your gun has tight frame/slide fit it is not gonna do any good there.

I have used buffers without anything inside since 2005. So far, one malfunction in matches : C-mag plastic tower broke - feeding failure 2007 so it has nothing to do with buffer. You should run lightweight carrier with empty buffer, with full mass carrier + empty buffer you may get problems. My setup weighs 6.7 ounces, complete bolt/carrier and buffer but no spring weight included.

Do not be ashamed ! Keep shooting CZ and single stack and you are gonna shoot more A classifiers soon

75.7439% Classifier, nice work Was it your best PD classifier so far ?

Please, do not do it and ruin your new gun... Use powders suitable for 9mm Major, N340 is not. You are creating 10.000+ PSI more pressure than (for example) with 3N37, which gives pretty high pressure level itself compared to many others.

RG, "UP" = Uronen Precision and "V3M" is velocity 3 meters from muzzle. We changed test ammo to factory made S&B Match w/ 52gr Sierra Matchking. MV depends little on ammo lot, but is usually 3300 - 3350 fps (published 3400 fps). I do not know about surplus powders, but few years ago I loaded my long range match ammo (2 different loads for a match) with 55gr Nosler BT + H335 and it clocked about 3350 fps (1021 m/s) from 18" barrel. I have never measured M193 from 20" 5.56 Nato chambered rifle to be as fast. Please correct if I remember wrong, but I think Wylde chamber was designed different thing in mind than ability to shoot 5.56 ammo. I remember, it was designed for high power so you could load 80gr MK to 2.50" for long range slowfire. It is generally way better accuracy wise than 5.56 Nato with mag length ammo, but freebore is way too long for magazine fed ammo and keeps pressure down. Why so many rifles use loose chambers ? I can think several reasons: -US rifle manufacturers want to ream chambers loose because of liability and true .223 Rem chambered rifles (both bolt action and semi-auto) are as rare as chicken´s teeth. In Europe, liability is not an issue because all rifles must be CIP proofed + nobody knows what is high power shooting. -Like twodownzero said, people want to use 5.56 Nato ammo and loose freebore keeps pressure down -Shooters do not know what is the difference and how it effects on their shooting -"It has always been done this way", AR-15 rifles have used 5.56 Nato chambers since 1960´s so why change ? What is long freebore doing then ? What we should think about, is what happens when primer goes off and we have quite hard-to-ignite powder like Varget. If we have bullet close to rifling, say for example .01" from rifling (=short freebore), we will have powder burning before bullet starts to move noticeably - which means that burning space does not grow much before powder is burning. If bullet jumps, say .10" (=long freebore), burning space grows 10x more before powder starts to burn, which creates very different situation compared to first example. Of course, the worst thing is when bullet is completely out of the case before powder starts burning effectively. With long freebore, you can put more powder and get more velocity, but it is not that simple. With .223, 68-70gr bullet and Varget, you run out of case capacity before you can meet muzzle velocity obtained with short freebore. If you just add more powder than what is reasonable, you are crushing powder grains and creating erratic high pressure spikes. Remember, when you crush or cut powder grain it burns very differently (more degressively) than it was designed to. Of course, you can meet and exceed short freebore velocities if you just increase col (=more powder space) with long freebore. Lets say, earlier examples had col 2.25" and you load to 2.35" - lots of powder space for Varget and it probably works fine, you can probably also get bullet bearing surface completely out from powder space. But with AR-15 you can do this only by feeding every round straight to the chamber. No magazine will take such a long round. Many high power shooters load long bullets with very long col for slow fire - they get more powder space and perhaps bullet bearing surface out from powder space - better practical long range accuracy, but do not try to feed that ammo from magazine. I have found that H&K 416 mags feed 2.29" ammo reliable but that is longest one I have seen so far. Yes there are some 7-10rd mags with very long possible col, but are they suitable for 3-gun / rifle IPSC is another thing... Plese note, that pressure needed to push the bullet into the rifling is usually many times bigger than pressure needed to push the bullet out of the case. Sorry, I just do not know how to explain it more understandable And no, QL can not calculate these effects. You should also note, CIP maximum pressure for .223 Rem is practically the same (62.300 PSI) as SAAMI maximum for 5.56 Nato, 62.000 PSI. M193 ammo I have tested does not exceed CIP pressure level from .223 Rem chamber, but clearly exceeds SAAMI maximum pressure for .223 Rem.

Power Pistol is perfect for Bowling pin loads... I can push 230gr bullet to 1020 fps from 5" Kart with PP

It depends little on how your mags are tuned, but CMJ loaded to 1.17" works perfectly in my mags / guns, all mags with steel spacer.

That load was earlier rifle test load for UP rifles. Velocities V3m from my memory : 18" 2890 fps, 20" 2970 fps and 24" 3080 fps. I tested around 50 barrels with that load. We were later forced to change the test load, one reason being 70gr VLD bad availability at that time. So I can not think of it as exceptional From internet, I can not find any load that would have been shot with .223 Rem chamber, 70gr VLD and Varget. Please provide a link if you were able to find such data ? You should also note, that 70gr VLD gives little higher MV´s than 69gr MK/CC with the same powder charge (at least) in .223 Rem chamber. You can not make straight data comparison with 69gr MK/CC or 70gr VLD, difference is something 20-30 fps. Many bolt guns for sale in US (for example Sako, Tikka) are also reamed very loose from freebore, like most US made AR-15 rifles.

Not really... I would say, just a little (25-30 fps) slower than LW50 barrels I usually use. Probably thing making difference is the chamber - any .223 Rem chambered barrel is fast when compared to Wylde or Nato. Specially when hard-to-ignite powders are being used, Rem chambering usually gives noticeably higher muzzle velocities with same pressure level and less powder. Alaskapopo, you could try more progressive powders like AA 2520, BL-C(2), Win 748 or H414/Win 760. All of those give me 100-120 fps more than N140 with 69-70gr bullets without case capacity problems. Even H335 gives little more velocity than N140, but it can be a matter of chamber.
