So I know you're not suppose to shoot .308 from 7.62x51 chambered gun, but there's no problem shooting 7.62x51 from a .308 chambered gun. Well I bought a MVP LC, advertised as a .308 on the website. Well I looked at the gun when I got it and it only has 7.62x51 stamped on it. 308 isn't marked on it anywhere. According to Mossberg's website it says .308 / 7.62x51. My question is, can I shoot .308 from it safely? Is the gun ready for either caliber? Anyone with the LC shoot. 308 regularly through theirs?
