I haven't used the 240 gr xtp's, i do use speer 240 jsp .429 using gn. sabot over 70 grs. of Pyro P. So far of the 5 deer i have taken with it, longest run was about 60 yds. I know it will bloodshot the shoulders if hit that area. Not real thrilled about that, may go to abit heavier bullet. I ain't into HP's at all on my deer.
