[QUOTE=Rn-85;1531134]I know that the dud rounds u was cycling through have scratches running the length of the case. This would indicate its catching on the mag?
My 222 did bind also, so I polished the living bejesus on the top lips of the mag. The mag metal seemed to be stamped with raw edges during manufacture with no or very little finishing. This did improve it but 600 odd rounds later if you don’t close the bolt like you mean it, you can still feel it grip. The thing that really got up my hooter was how it used to bind when charging the magazine. The binding combined with the strong spring was a pain in the arse. All good now, not perfect but got technique sorted.
