Thanks for the replies. The newer one is 30-60 and will not be re barreled. When hand loaded it is very accurate. The problem is when the bolt is stroked the cartridges will not feed, the follower and spring seem to hold them in the top of the magazine, but does not push them tightly into the magazine lips. The older one I am preparing to re-build it is a 30-06 and will become a 35 Whelen I already have a 24 in shaw barrel. Thanks
