Nitro in a BP revolver.

[vbull]

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...

Are you sure? What about Westlake and Anvil conversions?

they are still muzzle loaders where as the bp conversion is actual cf brass cases in cylinde
edit....
westlake are still loaded from the front into the cylinder and i believe use shotgun primers to ignite which are still percussion.
the bp conversion cylinder is strengthened and as a separate piece at the rear where they are 6 individual firing pins which are activated by the original percussion hammer

Ah ok. When the 209 shotgun primers were mentioned it confused me as this is what the aforementioned conversions use.

Ps You could have your 1858 converted to nitro

My mistake, as already mentioned, the back plate part of the conversions I referred to has firing pins and does not take shotgun primers. Sorry for causing confusion there, don’t know why I said that. I have edited my post above to avoid any more confusion...
