I built a single shot 300 win mag on a savage target action, went to the range this weekend to break in the barrel and ran into an interesting problem. The rounds arent being fed out of a magazine, just single placed into the action, so there is no upward feeding as the round is stripped from the magazine lips. This is causing a problem, when i push the bolt forward the tip of the bullet is catching on the chamber where it is cut out for the belt. Anybody ever ran into this issue? or have any ideas of how to remedy the problem. I just loaded up 208 A-max bullets for break in but i would think the problem would just get worse with a HP bullet.
