So first off I am new to muzzle loading and want to buy one of the kits in the link below, question is which caliber should I buy .50 or .54 Caliber ? I'm just a target shooter nothing serious just for fun and no hunting. I like the Lyman Great Plains Rifle and I understand that the Lyman is actually made by Perdersoli in Italy
