Maybe I have my answer
So, apparently the bottom rim is 13.51mm on both 7mm rem mag and .300 win mag? So, same bolt face? Is it the same bolt length, too, so basically the same long action bolt for both 7mm rem mag and .300 win mag in a Win Model 70 CRF? If anyone has both bolts and could check their interchangeability for me, that would be great. I also don’t know, just because I have never learned, if these bolts have adjustable lengths, or if headspace is established through machining the chamber. Forgive my ignorance, but I won’t learn unless I ask a question or two.
