After 123 rounds???!!!

My understanding, and in not a doctor nor do I play one on tv, just at home, is that as long as all of the dimensions are the same between the two bolts, they are interchangable. They headspace them with the extension and not the chamber cut. Being that there are type 1, type 2, and what I have read others being completely out of both specs, the barrel maker needs to have the bolt you are using so they don't send you a barrel headspaced for type 2 and you put a type 1 or other out of spec bolt in and blow up your gun.

Again I am not a gun doctor. I just play one at home.
