The only thing you might have to change out on the rifle is the nipple. If this is a factory nipple which I doubt. Some of the factory nipples were not the best. RMC Sports sells (or used to) Lyman rifle stainless steel nipples for the rifle.

Other then that they normally are great roundball shooters. I hunt with a person that shoots one and he has done some impressive shooting with that roundball rifle.. His is a .54 caliber but a .50 caliber will do just fine.
