Mine shoots the 240gr xtp in black short mmp12 sabot with 100gr Pyrodex P and Winchester w209 primers great, along with 80-90gr pyro P with 348gr powerbelts, 90gr RS and a 385gr hornady great plains conical. These are not picky rifles and its a lot easier to buy a package of different conicals and load up and go out shooting. Sabots you will have to play around with different sabots to find which fits the barrel and offers the best accuracy.
