I’d use 6.5 creed on anything, and game up here is bigger than most (northern Alberta). If I’m shooting an elk past 800 yards, I’ll use 300 Norma. 6.5 with 143 eld-x will do anything though.
I like my two Creeds both are 1moa or under and both have smacked with authority little Texas white tails while on foot stalking. I load 140 Berger hybrids they don’t mushroom but fragment by design positively deadly on white tails, got a feral with one as a opportunist it smashed the first shoulder and came apart in the boiler room looked like a blender went off. Dead piggy ran 20 meters then balled over and twitched. The Scandinavians swear by the 6.5x55 for their moose, reindeer and caribou not small critters by any means. The Creed duplicates the Swedish load in a smaller package.
