I am looking for some .25 stevens Long rimfire shells. I bought a box at a gun show and they all are duds. I pulled the bullett and the powder is good but the priming compound seems to have become in effective. Does any one have any shells or an Idea of how to :reprine" the priming compound on a rimfire shell.

We are trying to shoot a beautiful small frame Martini Henry made by BSA in this caliber

Thanks
Mike
