I decided to play around with some 300 blackout loads.
200 grain Makers Expanding Subs
10 grains of H110
2.20" OAL
Winchester Small Rifle Primers
Averaging 1057fps (10ft from muzzle)
Trued Remington 700 Tac
16" 300blk
100 yards since that is as far as I would use them.
Medium was a 1# bologna pack covered by a 10oz leather wrap. Backed it with a piece of 1/2" particle board and then several milk jugs.
Round penetrated to the 4th jug, damage to the first 2 jugs was substantial. The last 2 just had normal penetration holes.
I got expansion from 9 grains and up but the accuracy was best between 9.6 and 10.2 grains. Obviously 100% weight retention.
