I'm late into this one (as usual) and not exactly on point (pretty normal) but I run a 225gr. HAWK at 1900FPS with no pressure indication and minimal muzzle flash with Re12 in my T/C Contender "Super 14". Not sure what a rifle length barrel might give don't have one to check.

I have "CDO". It is just like "OCD" except the letters are in alphabetical order LIKE THEY SHOULD BE!
