I'll bet that load works like a champ, but you've got tougher eardrums than me. I like the .45 Colt in part because it gets work done with less fuss and muss. Never liked wearing extra stuff when hunting. I'm thinking a swap back to Unique--I've hunted w. 8-9 grains before--and that Sierra might be the best of all worlds. I just hope it shoots accurately.
