    308 Winchester (SAAMI) Gauges

    GO - 1.6300"
    NOGO - 1.6340"
    FIELD - 1.6380" Shop (Military) Gauges

    GO - 1.6350"
    NOGO - 1.6405"
    FIELD - 1.6455" There is a .013" difference in chamber length however, between these two "Safe & Serviceable" rifles!

    Do you have a military surplus rifle chambered in 7.62 x 51mm? If so, you probably bought it to get a "308 Winchester" at a really low price. Well, you messed up. It's like looking at a rabbit and a hare. They're close, but each is distinctive, and you have to understand what you're looking at.

    Yes they are different, but since SAAMI considers it a safe swap, what is your point about messing up?
