Stand up a 7.62x54R next to a 308 win.... You would swear that the 308 is just a rimless 7.62x54r....... Headspace isn't actually a problem - as the 308 has a chamber rim to shoulder dimension that is almost identical to the 7.62x54r...... The base on the 308 is a smidge smaller - so reloading the brass may be a bit of a challenge... but otherwise - I bet you could chamber and shoot standard 308 win all day long in a good Mosin....
It's nothing like the trouble caused by shoving an 8mm mauser into a 30-06 or trying to load 7mm mauser into a 7mm mag..... (I have found plenty of wrecked 7mm mauser brass at the range from shooting it in a 7-mag....)
Thanks
