Though I've never loaded the 250 gr regular XTP, I have done the 240 gr XTP Mag. My best load was 38 gr of Lil Gun with a Remington 7 1/2 primer and a tight taper crimp (.475). I seated them to 2.03 inches OAL just burying the cannelure for the taper crimp to bite into. Off a bench rest rig it yielded a 5-shot group of 1.3 inches at 100 yards. Best 4 of 5 was 1 inch and best 3 of 5 was 0.6 inch. I can't imagine that aside from different expansion characteristics, it would be much different than the 250, but I could be wrong. This is the same charge and primer that yields my most accurate 250 FTX load as well, other than the OAL.
