Scratching my head a little on this one but have some ideas and just want additional input in case I may have overlooked something. I have two .300 win mags, one is a 98 mauser and the other is an Eddystone Enfield. I am trying to work up some loads for these and have run into a situation where the 98 will function properly but when I shoot the same round through the enfield I have issues with the case clinging in the chamber (have to really pull hard on the bolt to eject). Any ideas? The load is 74 gr of IMR 4350 with a 180 swift scirrocco. Barrel lengths are the same and the same gunsmith built both guns but the enfield has seen more trigger time. I here how the .300 can errode the throat but not sure if this would cause the clinging or not. Any ideas would be appreciated.
