I think I've figured this out but just to make sure. I have a 22-250 in a long action. To convert to a 223 I'll need to get a short action bolt head and an extended firing pin nut. My question arises from the fact that since the short action bolt head is 7/16" thick and the long action is 1/2" thick how do you take up the 1/16" space with the short action head? I suppose this is accomplished by setting the 223 barrel back with a go gauge so the bullet will chamber to the proper depth. Before I try this just wanting to make sure the bolt will close and function properly. Am I missing something here?

Thanks in advance....Floyd
