Thanks Dan. I think I have looked there but I'll keep checking.
My barrels should be ready about now. When I get them I will finish up assembly and see about seating depth. I have some ammo made up with bullets seated long, and I can finish seating up at that point and test the loads. I'm starting with H4895 under 95-grain Partitions.
Since I started this thread, I found a good use for my stash of AR-Comp...pushing 70-grain Accubonds in my 5.56 hunting ARs. Works good there!
I'll post results when I can.
