I realize that a forum for primarily UK shooters is not the best place for this question, but maybe some foreign shooters might know.

I've been toying with the idea of buying a percussion revolver. One of the things deterring me is the fact that I have no place to shoot it, since I live in the city with no access to rural land, and I've never heard of a US indoor pistol range that allows black powder - it would be a rare outdoor range that did.

Hence, I'd own something that I didn't have much opportunity to shoot.

BUT, I've also heard of two US companies that manufacture cartridge cylinders that can be interchanged with percussion cylinders. Thus I could use the cartridge cylinder on a range, and the percussion on a rare foray into the open country: the best of two worlds, and I could still practice with it more regularly than if it were BP only.

Does anyone on the list have any experience with these gadgets?

Cheers,

Jim
