Knight TK2000 Muzzleloading Blackpowder Shotguns - Even if you've bagged countless birds with your shotgun, turkey hunting will never be the same for you once you try it with the Knight TK2000 muzzleloading shotgun. With up to 85% shot density in a 30 inch circle at 40 yards, it's superior to even the best centerfire shotguns on the market. The secret is the patented jug choke design. The jug allows the shot to expand, then redirects it into the shotgun choke tube, intensifying the pattern.
