No, the bullets I use cast at either .312 or .314 and I size down after powder coat to .311. Don't try to size up with powder coat, not a great idea. Only 7.62x39 bore I ever ran into that was .308 with the very first Ruger Ranch 7.62x39mm barrels - all the rest have been .310 or .311.Probably wouldn't hurt the accuracy either! AK barrels are notoriously loose. I've slugged plenty of them and they are so widely inconsistent! Snug fit is better!
Can you get .308 dia up to .311 or .312 when powder coating? Or is it too thin of a coat?
