Dose any gun maker chamber a rifle for the 7.62x54R?
I do not know if rifles are still being chambered for it in Finland. If the Russians are still making the Dragunov sniper rifle, then the answer is yes. But probably not a whole lot of them.
Those are the only two possibilities I can think of. I can see no reason why anyone outside of Russia would chamber this cartridge today. And Russia has so many metric tons of Mosins that they'd never have to make another one of the dad-burned things.....
