The gun hasn't been converted. the firing pins just happen to be rusted off at the proper length to work as a center fire. The first loads are loaded with 55gr Bp and 3/4oz of no 8 shot. I use an over powder wad a 1/2in thick 20ga cushion wad and an over shot wad glued in with a hot glue gun. Used once fired cases trimmed to get rid of the crimp. The firing pins look a little long but their not puncturing the primers. It will be interesting to see if the gun actually has any kind of a pattern. That will have to wait until after the storm.
