Think I have it figured out but I wanna make sure. I have a 12fv .308 and I want to switch barrels.
The case head for .308 is .473, so does that mean i can switch barrels with a .473 sized case head
and not have to switch bolts. And also what are my tolerances for case head size matching up with bolt.
I noticed the 22-250 is a .472.
