I have three of these Marlin .54 cal stainless muzzleloaders.I want to convert them to shotgun primers instead of caps.They were made by T/C and T/C brench plugs will fit right in.I just need to change over the bolts are mill them to have striker for shotgun primers.They are awesome guns I just hate caps.Has anyone else done something like this?

T/C has a Black Diamond striker conversion kit that uses 209 primers. These were for early Black Diamond muzzleloaders. I have seen it listed in the T/C catalog.
