Anyone out there shoot the Mossburg conversion barrel? I got one several years ago, and have not seen anyone else using one. I used it to kill a Moose a few years back. I shot it with a 355gr Buffalo Bullet, center of the chest. Litterally knocked him on his rump. I used 85gr of loose Pyrodex. The only thing I don't like about it is that it is harder to clean, since the breech plug is not removable.
