Why would it not be possible to take a T/C Encore with a Smith/Wesson .500 barrel and turn out a brass insert in the shape of a standard .500 round but about 1/2 the length? Set it up for a rifle or pistol primer and load as a muzzle loader with smolkless powder....actually a number of the inserts could be made with primers in place for several shots without re-priming a single insert. Looks to me this would be a simple safe way to have both; a muzzleloader and a cartridge gun all in one. Please let me know if any one is doing this and if so how is it working? Thanks in advance, Charles
