I just purchased a CVA 50 caliber Hunterbolt at Gander Mountain on Sunday. It uses no discs, has a 26" nickel barrel, advantage cammo stock and for $149. I shot it yesterday and at 50 yards with open sights, an 80 grain charge of 777 and a sabot with a Lee 230 grain, home cast semi wadcutter, placed all my shots under an inch.
