I found that the 240 grain XTP shot all right but I felt they could have done better. I was more encouraged with the 405 grain .458 diameter Remington FP (I also cast my own out of pure lead). Shooting 100 grains of Goex 3f they did well. I am sure the Barnes Expanders would do real well also, but they are expensive to shoot.
If I come across a good shooter, I will keep you in mind.
