So I just bought a rifled/canitlever mount for my Mossy 500 and I will be sighting it in this weekend. As I look around the internet I keep bumping into the .50 cal. muzzleloader barrels that are for sale that convert a 500 into a ML. Has anybody here ever tried one of these? It would be interesting to use one and realistically that would turn my shotgun into a truly "all around N. America gun." It seems that these barrels can be readily had for less than $100 and it would make a great replacement for my confounded .54 cal ML.
