For me, my most accurate handload so far has been Xtreme 124 plated HP’s. At 10 yards the group is 1/2 the size free hand, even tighter off a bag that BB 135’s. I tried many OAL’s, crimps and power factors and just couldn’t get them to group as well as any plated bullets I have loaded. I like the economy and ease of handling of coated bullets over plated; I can easily grip and manipulate coated bullets with two fingertips, the plated bullets feel slippery. That makes my RPH a bit higher,.

Make sure the primer punch block assembly is fully seated—use a 9/16” wrench. I have had intermittent high primers since my 650 was new. I attributed it to technique and speed, but today I all at once every round had a high primer. It turns out the punch assembly was about ready to fall off! https://forums.brianenos.com/topic/238771-650-and-high-primer-issue/#comment-2661223

Anyone have one? Tried one? I held one at the LGS yesterday. It felt solid, has LRBHO, and the handguard is long, slim and feels light. The mag catch is very easy to use— not like most of the Glock pattern rifles I have played with. I didn’t even touch the trigger, so no idea what it’s like, but imagine it’s basic mil spec. https://diamondbackfirearms.com/collections/db9r-rifle-series/products/db9rbb?variant=1953441513484

Just can’t wait until Graf’s does one of thise free hazmat with 10lb purchase....

Is it necessary to neck size 223 for 3gun hoser ammo? Will be shooting for minute of IPSC target.... It seems I could process my brass a lot faster and with less effort with just a decap and FL size. thanks.

I believe 88’s at 1600 fps would give a pf of 140. I shoot some falling steels that .22’s will knock down, so a powder puff round would work in that series. Power factor for USPSA is 125 for minor, 165 for major.

Anyone tried them in a Colt pattern PCC? I am running BA barrels. (I actually did trya forum search) thanks

Darn it! I missed it.

Can somebody explain in idiot terns what this does? Is it a worthwhile modification? I tried a search and only came up with vague references. thanks

I have also noticed negligible peening if the bolt face of my Versamax. This can easily be sanded off and polished. I check the bolt face fir deformation whenever I clean it, and have to sand/polish every year or two, but I only manage to make about six matches per year.

I have been using a Rock River for about a year in a form 1 rifle. It has proven reliable for me, just you cannot rest the magazine or torque it in any way. The issues I have had with that rifle I can directly attribute to 1) the light trigger in it has made for a feew FTF's, 2) loading ammo too light to properly cycle or reset the trigger, 3) getting crazy with the recoil system. I am no longer trying to load it to make is shoot like a .22. The gun will need to be cleaned more frequently than a .223, and the magazines will need to be cleaned on occasion.

did you use extrapower springs?

Thanks for the input. You all were correct: barrel shot out. He sent it in to BCM and they borescoped it. They are going to replace it for him.

BCM chromlined, probably about 5,000.

We attended a rifle hoser match this weekend. My son shot his personal duty rifle. I noticed two sideways bullet holes on the first stage, but thought he must have tagged a stage prop. On the subsequent stages, it started doing it consistently after fourty rounds. He had initially shot with his .30 cal suppressor, so we assumed it had a baffle strike. He took the suppressor off for the last few stages, but it continued. Always after right at fourty rounds. After the match, he did a few mag dumps. No keyholes after a thirty round mag. So he loaded up a big mag, and it started keyholing again for the last several. Any ideas on what could cause this? The flash hiderhad no fouling that we could tell, and as it is for a .30 cal, there is ample room to clear the bullet.

I agree that it is most likely a magazine issue. I have had the same problem like three time (of course always during a match). I have started tracking which mags give problems...

USPSA says PCC's requires be shouldered, but no penalty mentioned for not shouldering. USPSA PCC Adendum

I got one to use with my PSA Colt mags. I connected two 32 rounders because that's all I own. At first the free spring was somehow getting past the floor plate attached to the other spring. I played with it a bit and got that figured out, but then either the floor plate or follower, or both are dragging. I beveled both a little bit, but they're still dragging. I eventually quit, because you need at least three good, working hands and I only have a bum finger on one hand. I'll try again later this week, but if anyone has any idea on what to do about the dragging follower I'd be all ears. Thanks

I sometimes run a Rock River mag block--bottom load. I have had a few problems, but I'm not sure if it was the conversion or the loads I have been using. Reloading in a converted rifle is more difficult, and if the mag bumps a barricade, or you try to use the mag as a monopod, you will experience feeding problems. I also own a dedicated Colt stile lower, but have not experienced the doubles, but I have only shot it once or twice resting on the magazine and did not experience problems then.

So what luck did you ever have with this coupler 32 rounders? I want to try one of these. Probably won't load more than 50-55 rounds.

For America's birthday: Flag PCC

I run two set ups: JP bolt with carbine buffer and MFA modular bolt with H2 buffer. Both use a carbine spring, both run light charges that make 126 PF in an 11" barrel. My heavier set up is still 6 oz less mass than the one in question. The lighter set up is on a standard 16" upper, the heavier in on a 11" SBR that I run suppressed frequently.

Yes. What Eric said. More precisely what I meant to say was that the base plate is fully seated on the magazine. I was able to tighten the locking screw on mine without complete seating and the spring was sticking and I could not fully load the magazines.

Try tapping the base pad on more--I had to use a plastic tipped mallet to get my TF extended base pads fully flush on the magazines. Also remove the retaining plate from the springs before installing the base plate.
