So I bought this older 111 in .300 win mag. I wouldn't shoot and I wanted to convert it to .308 Norma anyway so I bought a Shilen barrel and installed it. I couldn't get it to head space so I took it to my retired gunsmith friend with the barrel wrench and he discovered that the front of the bolt lugs are contacting the rear of the barrel before it headspaces. In other words (I think at least) the bolt face is too deep! Has anybody ever heard of this? We fired it with primer only and the primer backed out about .015ths. After I got home I looked at some of the Win mag brass I had fired and the cases do look a bit stretched. So I am going to order another bolt head and in the mean time stone off the front of this one. It is about .112 deep. Does anybody know what is the desired depth?
Has anybody ever heard of anything like this? What did you do?
