I’ve shot surplus 7.62x51 through mine and had no problems, granted the bolt is a bit stiffer to lift up sometimes but functions fine.
I almost bought a Ruger Gunsight Scout rifle but my friends rifle will not function at all with surplus ammo. I bought a Tikka T3x Battue instead. Lighter and way better sights. Only down side is plastic 5rd mags that cost 100 millions dollars each.
