I need some help!!! I swapped my 22-250 barrel out for a 7/08. I also added a new Boyds stock. When I was using my 250 barrel w/ the Boyds it fed fine. It won't feed the 7/08. The case head dips half way through the cycle and allows the the bolt to pass over catching the round mid case. Do I need a center feed for 308 or would they be the same. Thanks for any help
