bingo! scrubbed the breechface with a nylon brush and gave it a try. hicupped a bit on the first magazine, then put another 250 rounds through it with no problem. thanks for the assist!

thanks for your post, quick answers to your questions below thank you for the advice, I will take a look at the breechface and barrel attachment screw and see if I can find a remedy in either of those.

after a few magazines, my buckmark started going click instead of bang today. misfired rounds show some firing pin impact (tho subjective assessment at the range was the dent was not as deep as a succesfully fired round). I did the usual prreventive/remedial maintenance (cleaned out the chamber to make sure a build-up of wax or other crud wasn't preventing the round from fully chambering which could lead to a buffered firing pin strike as the round completes chambering on firing pin impact, checked the bolts on the top rail to make sure they were tight, tried a couple different brands of ammo to make sure I hadn't gotten a box of ammo which just didn't make QC). still no joy. anyone have a decision tree they'd recommend to diagnose this, or maybe just the name of someone who does reputable basic work on buckmark pistols? thanks in advance.

that's my standard load for a hornady 55gr fmj. I can get less than inch from that load when I'm shooting off a rest using a magnified optic. i've never bothered doing a ladder test since I don't need more than that for practicing field positions @ 100 yards or less.

ahh, bummer to hear that these's aren't 100% for blackout brass forming - that's where I was really hoping they'd help out. So far I'm just using them for 5.56 (want to get through my 5.56 case processing before switching toolheads) and they're doing fine for that but as you mentioned, that's really just light trimming compared to carving off .4" of case neck. Oh well, was worth a shot. I'll give them a try on blackout forming just because I feel obligated to pee on the electric fence myself, but at least my expectations are already managed about chances for success. thx for the heads up.

any pics or background info on those? I always thought whoever did the propwork/technical advising for that film did a great job. really liked the full profile comp on the beretta, have never seen one for sale anywhere. Sent you a PM with the info on the SGS full profile compensator. This is one of the one's I put together just for giggles: Very nice, thanks for the info!

set up the brass prep toolhead and tested out the MSC cutter, works perfectly. Notar - are you making 300 blackout for yourself or selling them commercially?

needed more airflow to carry away chips.

thanks, look forward to seeing them

MarkCO - can you tell us whether the handguard is drilled to accept the JP/VTAC small rail sections for mounting lights/foregrip/sling mount etc?

thx for heads up, i've got a pound of reloader 15 on the shelf waiting to try out some loads for a 75gr hdy otm.

all wadcutters I have loaded for .38 were bevel base, so only a slight case bell was required in order to seat the bullet without any shaving. a bit more bell may be helpful in getting the bullet started if you are using hollowbase wadcutters (i.e. no bevel to assist in setting the projectile into the case mouth). my $.02.

pediatric dental visit(s) burned up a lot of shop time this week so haven't had a chance to set up the .223 brass prep toolhead. should have an answer next week, will post back.

hi merlin, photo I'd originally posted above shows a bunch of .223 in the output chute (pic is in my post alll the way at the top). I did not have a .223 rollsizing die, so shimmed out my 9mm die by .015 and had a case-feed bar fabricated to feed them. Chills - have not done any research to determine whether roll-sizing extends the useful life of rifle brass. Have read from others on this forum that roll-sizing does extend the useful life of oipen gun .38 super brass by "reconditioning" (i.e. tightening up) the primer pocket which would have otherwise become too loose to hold the primer after repeated firings. FWIW, I'm roll-sizing rifle brass strictly to improve reliability. I went through the tedious task of case-gauging about 1000 full-length resized (but NOT roll-sized) cartridges to test the configuration of my case prep toolhead. What I found was that the only failures I had were all at the cartridge rim where it appears that the extractor had yanked a bit of the cartridge rim out of spec (or a combination of chamber pressure and a loose boltface tolerance had allowed the case head to expand just a thousandth or two beyond the Wilson gauge I was using). When I roll-sized all of these cartridges, they then passed the gauge without a problem. Re: M249 cartridges, I have read the same advise (avoid them if possible). For better or worse, I really don't know what weapon fired most of the brass I get as once-fired so I just inspect them and discard anything that looks damaged. Re: trimming – yes, you have to trim brass (or at least roll-sizing does not remove any need to trim brass). I have an RT1200 trimmer on my brass prep toolhead and run everything through the trim station after full-length resizing. If the brass has grown long enough to extend beyond the SAMMI trim-to spec (to which I have adjusted my trimmer) then it gets cut down. If not, then it just passes through the trim-station unaffected on it's way to the output chute.

hi guys, the correct replacement part appears to be MSC part # 78232089 They're $8.70 each in qty less than 10 from MSC, maybe not such a huge savings if you're just trimming .223 but if you're cutting down cases as part of a wildcat forming operation than you'll go through cutters more frequently. I've just got a few in, they install properly in the rt1200 toolholder but I haven't had a chance to try them out. will post back and confirm whether they work. BTW - shadowride, this part has an 11 degree lead so there's actually a "front" and "back" side to it so for better or worse you only have 3 usable sides, not six. If it had no lead, then when you index the cutter down onto the cartridge neck it would impact the flat surface on the bottom of the cutter (and would not trim effectively).

that looks like a lot of fun - did you happen to catch what caliber/cartridge it is chambered for? Thanks for the photos and write up for all of us who couldn't make it out!

it's hilarious read that FX renewed it for another season but don't know when it airs.

* supposed to hit stores in a couple months and if you order now, elvis will personally deliver your scope when it's available...

what do you mean!!? at shot last year, they said it would be out "real soon"

I've had Ranier plated bullets lose their plating and destabilize in between 25 and 50 yards when loaded to 1150 fps with Alliant Power Pistol. Specifically, 25 yard test groups from a glock 26 were an acceptable ~3" group, 50 practice on a gong went (with this particular lot of ranier 115gr tcj's) from consistently hitting a 10" plate to missing the broad side of a barn. finally put up cardoard backers every 5 yds from 25 to 50, discovered that the bullet was shedding it's plating around 30-40 yards (indicated by small jacket pieces marking the cardboard or in some cases left in the cardboard) and once this happened the bullet went MIA. groups at 50 yards were around 2' from this lot. for the hell of it, i loaded a bunch down to around 900fps (not very useful as I was not running them suppressed, but rather just wanted to see if plating failure was a function of rotational velocity). At 900 fps the problem went away. From this, my assessment was that the plating failure was likely the result of a QC issue with this lot, as other lots had stronger/more resilient plating that did not fail at the rotational velocity of my standard (1050fps) 9mm load. I don't think we're disagreeing regarding performance of plated bullets at slower (subsonic) speeds - my comment above says that loading plated bullets reduces chance of plating failure (just as loading them faster increases it). WRT to tumbling, I tried berry's after I finished up my supply of Raniers and found the Berry's to be very crimp sensitive. Specifically, I loaded test lots of berry's 115gr after some small runs using jacketed WW projectiles and found that projectiles were tumbling (keyholing) at 7 yards. I ran a couple of more sets incrementally backing off the crimp and found that the keyholing stopped when I was applying very little crimp. whether this was typical behavior for Berry's 9mm bullets or just another lot-specific QC issue I did not know. for me, that bullet's apparent crimp sensitivity wasn't worth the aggravation, and I went back to using Raniers for a while as they were (at that time) still less expensive than jacketed projectiles. neither experience indicates that plated bullets are unusable, but each of them gave me reason to believe that plated bullets or either more finicky than jacketed (i.e. have a narrower range of loading tolerances under which they will perform) or they are just more prone to QC issues (i.e. WW may screw up jacket concentricity on a given batch but they'll still shoot "okay enough" to avoid hitting the target sideways). Both of my poor experiences with plated bullets were back in 2002-2003, at which time there was (I recall) a big enough cost savings using plated bullets to make them the more attractive choice. at this point, ranier bullets are almost they same retail price as WW or remington (and they're actually more expensive than jacketed projectiles if you're buying wholesale quantities) so I'm not sure I understand what benefits they offer.

thanks guys - just to clarify, concern about primer depth wasn't with respect to accuracy but rather safety. While I want my ammunition to be as accurate/consistent as possible, I'm not trying to produce benchrest-precision rounds using mixed headstamp brass and volume-thrown charges. Rather, concern was what (if any) is a "standard" for primer depth below flus to prevent slamfires. I'd adopted .005 simply because it was what I measured from M193. What I'm hearing from others re: optimal depth ranges from flush with cartridge head to deep enough to catch with your fingernail. Fair enough. I'll stick with looking for something below flush, but maybe only because it satisfies my deep seated paranoia about floating firing pins... Also - found an interesting bit of info re: where my high primers came from. As I mentioned, what prompted this question re: optimal primer depth was a recent spate of high primers I encountered when switching over from WW small rifle to Remington 7&1/2's. I recalled reading in my RF100 manual that a different stabilizer plate was required when using remington primers. I called dillon and spoke with Lee, who explained that they'd found Remington primers to have a taller cup than winchesters, hence loading remington's required swapping in a different part (stabilizer plate 17295) to provide more clearance. I don't see myslef buying any more remington primers now that WW are available again, but good to know that if I do have to swap back and forth, no question that I'll have to adjust primer seating depth.

PM me your address for ammo.

my $.02 - i would be very careful running berry's (or any plated bullet) through your suppressor. loaded subsonic, you reduce your chances of having them tumble or destabilize but an overly aggressive crimp can screw then up badly. Fired out of an unsuppressed weapon, worst case scenario is a frustrating day shooting innacurate ammunition that keyholes or otherwise comes upart under load. baffle-strikes would make that much more expensive and aggravating.

i agree 100%, Unfortunately, I see it more than i would like in our industry, as suppliers/manufacturers are aware there are backlogs and shortages of various components and know full well that your options are very limited as a consumer for large orders of some items. I'm seeing this specifically with a bullet manufacturer and it pisses me off to no end. If I could take my business elsewhere, I certainly would, but in the end my options are few:angry:
