Tried 14 grains trailboss with 196 grain full metal jacket projectile today averaged 1190 fps for 5 shots 14 grains was a 70 % load so will keep working up a grain at a time
Question, does it have a small diameter smokeless firing pin?
If so, that would keep me to light loads, something under 30,000psi. & closer to 25,000psi. Trail Boss will do that with a jacketed bullet and 100% load.
A .300 Win Mag loaded 100% Trail Boss with a 180gr. jacketed bullet made 28,000psi for Hodgdon.
