[QUOTE="lancetkenyon, post: 3068244, member: 68875"] Depending on the bullet in your factory ammo, that might be your limiting factor too. If they are a big round nose bellut, you could be engaging the lands of the bore before you get the bolt closed. When you pulled out the round you attempted to chamber, could you see some scarring on the bullet from the lands in the throat? Might be as simple as seating the bullet a bit deeper to push them away from the lands if this is the case. Looking at some of the Sellier & Bellot and PPU ammo offerings, this could be some of the issue. If you can get the bolt to close, chamber a round and go fire it. It will form to the AI chamber. You will get something like this when done. This is .260 Rem to .260AI, but same principal. Mine is a crush fit too. Definitely feel the bolt face draging on the case head. Loaded parent case round goes in, BANG, empty comes out reformed. Since you have factory ammo, this is the easy button as long as you can get the bolt to close. [ATTACH type="full" alt="20220205_080851.jpg"]556974[/ATTACH] Fire forming can still be plenty accurate. [MEDIA=youtube]oFW2pIvmz0Y[/MEDIA] [/QUOTE]
