I just picked up one of these rifles today from a guy on a trade. he told me it was a mosin nagant but when I saw it I new I wanted it. I don't know anything about it other than what they sell for. Is this a good rifle to shoot or should I trade it off? the ammos hard to find and kinda pricey. Any advice is welcomed. its numbers matching and its not sportarized its completely original from what I can tell.
