start about 79 and work up. Every rifle is a little differentAwesome data...Thx! I’m waiting on a 0.310” bushing, and hopefully run my ladder this weekend on ADG brass.
So no pressure signs at 83.0 grains; that’s awesome!
with your seating depth, you’d be running about 0.090” jump in my chamber. my chamber was done with a brand new reamer from Rich, by StraightJacket Armory. And I’m showing 2.998” to the lands with a fire-formed modified case by Copper Creek. So I’m planning to start about 2.940” BTO (0.050” off). And hopefully I can get to 83.0 grains with no pressure as well.
