Excuse my ignorance, in terms of projectile speed what is KRPM?
ID expect 4350 to be way to slow same for 4831.
Hornady Data for the 80 gr GMX suggest that Hodgdon Benchmark may be near optimal in terms of velocity Thinking on the order of a 28 grain load ladder.
As for Ball powders Ramshot tac looks to offer the top velocity for the 80 GR GMX Thinking 31 grain load ladder here. If I understand correctly GRT does not allow for Ball propellants.
Must Admit I am curious about IMR 8208 XBR as well. Generally very close to H4895.
Thank you!
