I might fool around with different bullet shapes when I get a chance, but for now I'll keep running the mg's. If it ain't broke...

I'm running cmj's which are probably a little longer, so I guess we are pretty close on oal.

Thanks, another RO told me they've seen that happen a few times during unload and show clear!

I got a chance to shoot the gun today and it ran everything I put through it. From 1.100 to 1.145 without any problems. I'll probably keep them on the short side just to be safe. Thanks for your replies.

Thanks Bill, I had a hard time believing that they had to go that short and still others had no problems shooting factory ammo. I loaded some test rounds @1.100 with 3.1 titegroup as a starting point.

I'm trying to build a load up for new PSA AR-9 and I can't get a good plunk test spin until I get down to 1.100 with MG 124 CMGs. I've read a few others that have to go this short, but more often I hear guys running factory ammo with no problems. Anybody finding the same thing? Thanks
