Basically what i could tell you is that the .452 - 300 grain XTP is somewhat a universal bullet used by many. The XTP does stand up to high velocity as well as the XTP Mag. For years they were sort of my standard test bullet for antything I might shoot weighing 300 grains. You should have no problem with their accuracy - they do shoot well.
A lot of people have hunted with them and the XTP mag very successfully for years and killed a lot deer. I do not myself use them for hunting, I have on occasion have hadbad experiances with them separating the lead from the copper when shooting thicker skinned animals like elk - no problems that i know of shooting deer.
