Round #2. So I put in the o-ring to help with the extractor (#60, pack of 10, at homedepot $2.50). Holy crap. It's like a whole new gun. With XM193, not one FTF,FTE, every one chambered. I went through about 200 rds yesterday. With the XM193 ammo, I couldn't notice it but my buddies could, 8-10 inches in front of the barrel a large flash from the ammo. Pretty cool I must say. At 100 yds, with a red dot, we were picking off 4x4 tiles. Not bad with a cheap red dot (poor glass), it was way better at 50 yds. The only thing I noticed was it would not chamber my reloads. It would completely jamb up the last 1/4 inch or so, I would have to hold it by the charging handle and wack it with a rubber mallet on the buffer tube (try THAT with a rifle) to pull the round out. Happened with the first two reloads so I quit trying those. They work fine in the AR they were shot out of before so I might just have to adjust the die (yes, it is a full size die) or just keep these separate as reloads. I also did try some BVAC ammo. Towards the end of the day, maybe 1 out of 15 would jamb up like that (BVAC are reloaded Lake City). It might just like XM193. Oh, well, I just bought a case from AIM last week so I'm GTG for those. For those that care I also got my 7.62 upper dialed in. At 100 yds we were picking off cartridge cases on top of the target board. It was a good day.

EDIT: It was my dies. I changed from reloading 38's to .223 and I must have moved the resizing die. I tried some of my older reloads and they load fine. It was only the last 200 or so, damnit
