H4350 and the 6 creed go together like peas and carrots.Every 6mm cm I've played with, 6 or so now, throw 41-42gr H4350 in there with a heavy for cal high bc bullet 30-50k off and shoot half minute groups. The 65cm has required more tweaking. I've had no issues killing deer sized game at shorter distance to beyond 700 with the 6mm. I think it's a fantastic cartridge.
