Best Powder for short barreled 300 win

[Doc Holliday]

Looking to try a new powder for my 22” 300 win with 165 grain ballistic tips and accubonds.

With the shorter barrel I think I need a faster burning powder than what I’m seeing in most published loads. Was also thinking of a round or short cut powder, but not hung up on that

Currently have RL 19, RL 15, and Big Game. Was looking at IMR 7828 ssc….

What powder do you think would be most suitable?

They will all work fine. Let the rifle tell you which it likes, but don't think the missing 4" is going to affect the burn.
