300 BLK bolt load data?

Supersonic. 110 Barnes bullet to be exact. R700, 16 inch barrel, shoot almost everything with a can but subsonic doesn't have the knockdown power I want. Used h1000 powder in the past (and thankfully still have some)
 
For the supersonic 110s, lil gun, h110, w296, rl7 imr4227 or similar tends to do very well.

For subs and cast bullet quiet loads, the bolt gun really shines. A light 90xtp and trail boss, red dot, American select, unique etc are much quieter ways of doing it since you don't have to run the ar15 gas system with a ton of gas.
 
The 300 Blackout I loaded was a stiff dose of H110 behind a 120 Barnes tipped bullet. Hell on Whitetails and the bullets are in stock at Midsouth currently.
