A firearm made for a nitro load is deemed fit for use with BP - indeed, many replicas of rifles can shoot both types of cartridge safely - Trapdoor Springfields [with lead only], Sharps, Smith, Rolling blocks, High Walls et al, ALL with lead projectiles, but not the other way around.


tac, can you support these two claims? Seems to me that nitro proof testing a gun which already has BP proof marks is no more risk than nitro proof testing a gun which has no proof marks. And exactly what law is broken here? Just trying to learn.

Completely understood
