I have a .58 cal Hawken rifle with a 1-48 barrel. I can throw rocks straighter than this thing shoots. It was an impulse buy, always wanted a 58 Hawken. So anyway I thought about rebarreling with an aftermarket 50 cal. The question I have is the Green mountain barrels are 1-28 twist. So will I be able to shoot patched round balls in this, or conicals , or will I have to shoot sabots and pistol bullets. I dont want to I am kind a traditional guy. thanks E.
