[QUOTE="Saskquatch6, post: 2082978, member: 58704"] If it were me I'd be starting load development over from scratch - given all the signs of over-pressure (and we haven't yet mentioned the likelihood of loose primer pockets). Start with new brass (preferably) or once fired (that will chamber without first being resized and does not show any of the pressure signs mentioned) and use verified starting powder charges (published/manual) for the given bullet/powder combination. Check primer pockets and ensure primer is seated as mentioned in previous posts. If everything is in order I'd expect things to normalize and you can build your load from there watching closely for any pressure signs. Stop when any signs of pressure occur and back down your powder charge .3 to .5 grains from there. If a fired case from the new starting load will not chamber even after running through your resizing die then your sizing die may not be set up correctly or there is a mismatch between chamber and die (likely) meaning your rifle may have an undersized chamber and your sizing die can't sufficiently size the brass for it to chamber properly (had this issue with an early production Win Mod 70 - 300WSM). Good luck with this [/QUOTE]
