Thought I would update this a bit. Gun has been restocked,brass shells were modified with a brass insert in the primer pocket (as per Tinkers suggestion) and work just fine,I'm in the process of working out a load.My only concern is i dont seem to be getting the velocities I see on other threads. I am using a 685 grain round ball and FFG Goex and 1 1/2 Swiss. With 5 drams and 5 1/2 drams im still under 1100 ft/sec. Should the velocities be higher for the amount of black powder ?
