As most of you guys know, there are several companies in the US that manufacture nitro conversions for most BP revolvers. The frame and barrel of a BP revolver will apparently take the extra stresses of nitro but the cylinder will not which is why these conversions are basically a stronger cylinder and separate back plate which holds the shotgun primers. If you look at the cylinder walls on say a 44 BP revolver and compare to a 44 nitro revolver cylinder you will see the BP cylinder walls at the front are thinner. Edited in: Just to clarify, the back plate I referred to above DOES NOT take shotgun primers, they have five or six firing pins depending on which model of conversion you go for. These conversions I'm talking about allow the use of metallic cartridges. Sorry if I caused a bit of confusion there, I think the lockdown is getting to me...
