My dad shoots remmy corelokts 180 grain. Shoots them well. Gun has been used for deer, antelope, coyote, and hog from 12 yards to 260 yards. The 180 is probably a little big for all of them, but it isn't bad. The gun shoots them well, and they're easy to find. I'm sure there are better bullets out there. But that gun is for hunting, not for groups off the bench.
