You can never interchange anything...except when you can.
Lots of guys, like me, have shot .308 dia bullets out of their 303's, designed for .312 bullets and found they work just fine.
I know more than one person who shoots .311 bullets out of their worn .308 win and .30-06's to regain some of their lost accuracy instead of buying a new barrel, and one other fellow shotting 123 grain .310 TSX's (meant for the 7.62x39) out of their M14 (.308 bore) since they simply couldn't find any TSX's in .308 at the time.
And then there are cast bullets, where the last thing you want to do is shoot a .308 dia bullet out of a .308 dia bore....
So, I hope that clears everything up for you...
