Yes, I am running 95 grain Montana Golds at about 1500 FPS. It is putting them in a ragged hole at 25 yards, and really not much bigger at 50. This setup is light years better than my 5.5” comped, sleeved barrel. It crazy flat. I have a few ideas I am going to develop this winter, by spring I will have the ultimate pcc blaster!
I have not had time to mess with the guard. I will be getting back to it in October.

Same weekend as Area 8, so sadly no.
I feel your pain.

I had a few mags swell after quite a bit of use. They would drop free when I first acquired them. I threw them in a milling machine and thinned them down a little. Probably several 5 gallon buckets of ammo later, they are still working great.

Works for me. My friend who shot the video has laser envy.

Hope to shoot some video later today.

The popple hole barrel is a spinta I purchased on sale last year. The pic above is a generic barrel that I chopped and threaded, then designed my own comp. I tig welded a sleeve to that and did a pin and weld.

Once again you did something really cool.
How large are the ports? At 1235 fps I assume you are loading 115 gr bullets, right?
Keep up the good work and thanks for sharing.
.215”, and 115 grain billet.

I made the mistake of wrapping my thumb over the “exhaust port” once. Very uncomfortable, made my thumb black, but everything was still intact. Not going to do that again.

That is awesome!!!

My home made laser. I got sick of my purchased lasers losing zero and the batteries going dead. This is a very rough prototype. It looks like hell, but it works great.

Going to machine a hole in it and put one of these on.

I didn’t get to put a lot of rounds through it. It seemed to flatten it out. Recoil was roughly the same.
-
I have wanted to try this for probably a year. Velocity drop wasn’t as bad as I thought. 1235 before the three holes, 1218 after.

A big thanks to Howard and the York crew for a great match! I had a blast even in the downpour.
Thanks again

Crap, I was all excited about long range slug targets!
-
I just shot some slugs out of my vepr at 150. The drop wasn’t that bad, I was making decent hits.

Then it’s back to Production.
The PCC addiction is pretty hard to beat. I said that about open a while back. I think my comp is full of spider webs.

You would have to take off the ejector on the stern block. I THINK it would work, or at least modified to work. I have a guard bolt and barrel, my friend has a stern Glock mag block.

So what worked?
I caught a very good deal on bullseye powder. I found a load that I am happy with and have been using it. Not sure it is the best, but it suits me fine.

Wonder why WAC/HS6 wouldn't burn completely in a longer barrel, and yet burn
completely in my TruBor 5.5" ?
I am guessing, the trubor has a locked breach, the bullet has exited the barrel before it is unlocked. With the blowback, there is not a locking mechanism, it is just relying on the mass of the bolt to hold it in battery. Pressures are still higher when the brass is coming out of the chamber, essentially blowing gas and carbon back in the gun. My blow back rifles brass are always has more carbon on them than my open gun has. I am sure it can be explained more elegantly than what I am doing, but that’s my guess. Give it a try, maybe it will work for you. They made a hell of a mess in my gun.

Might depend on your load - slower powders and lighter bullets
just might get a comp to work efficiently
That didn’t work that well in my blowback guns. I tried autocomp and hs6. I had a tremendous amount of unburnt powder in the upper and lower.

I have had an opportunity to play with the Ruger rifle. My friend purchased one. When he brought it to my place, I honestly thought what a turd. Then I shot it. It is a very fun little rifle! The stock fit me great, and to me it shoots soft enough. I did not have a chance to shoot groups, but seems accurate enough from what I seen. I popped off the rear sight and made a RTS2 mount that bolts on, that optic seems perfect for it to me. One disadvantage, in my opinion, is putting the safety back on during a course of fire. When I have to run any distance in a stage, I usually flick the safety back on my Ar pattern rifles. I took a nasty fall last year in the WPA section match and I had the safety on when I did it. The Ruger will not be as fast and easy in this respect. I think it would be a fine rifle for the steel challenge. To summarize, it is a fun little rifle, but in racing applications for me, I prefer the Ar style rifles.

1.025 is my OAL. I didn’t adjust my dies from the115 grain fmj Montana Golds I had been using. I run an EGW under size de-capping die. No issues so far.
