i will try backing it down to 110 gradually. I haven't tried that. i have the remington 250 gr that came with the gun. i guess i could try them as well. also, i've heard that re-priming the UML brass has its limitations ... i don't understand how it would be any different than any other brass?
It all has to do with head spacing of the brass to the nipple (breech plug). When the bolt is closed, it should be compressing the nipple to the inside flash hole in the brass. That maintains the "seal". After compressing the brass casing a few times, the brass compresses with a "memory", which will start letting gas escape, thus gas cutting the breech plug nipple. Once it starts, it'll only get worse and the plug will require replacement. You'll know too, as the gas will start escaping from the gas port on the action.
