I make the muzzle coning tool and calibers in order of popularity are .50, ,54 and .45 (about equal), .58, .40, 32, .36, and .62.
I really like the .54 for hunting mule deer. I always felt it a tad light for elk so use a .58 for that job. I’ve also shot a lot of deer with my.50 but since I’m a lousy shot I just never had the needed confidence in it though it’s a great all around caliber.
