I have seen one post on here where a person cut down a 50 caliber encore barrel for a black powder pistol, and I found on that is a decent price that is used. Instead of carrying my bp rifle all over the place during muzzleloader season, I thought this was a good idea, as it is much easier to carry one in a shoulder holster, and have access to it, as opposed to slinging on and off a rifle. Any feedback, negative or positive, on this? And what would be a good barrel length?
