While roaming the internet, I see that surplus 8X57 ammo can be J or JS, .323 or another round that is smaller .318. I've also seen the comment that the barrel needs to be measured (slugged) before using the bigger round.
Can someone enlighten me on this, how do I measure it and is there a real issue? My Mauser is a take home, 1939 vintage all German 98k.

Thanks
John
