I just started loading for my 110 in 30/06 and am getting flattened winchester primers (although they seem to be pretty soft in other calibers), and bulging above the web. One round was slightly difficult to eject. Loading IMR4064. My Lyman #49 manual says min is 48g and max is 53g. I loaded between 49 and 51 in half grain increments, and am seeing the same signs from all weights with the bulging being slightly less on only the 49g rounds. This is the first time the brass has been reloaded.

Could there be something up with the rifle since I'm having problems so low in the load range? Cases measured 2.492 before and .000-.005 longer after shooting. OAL was 3.207, the manual called for 3.200.
