The cannelure on 158gr. XTPs sits higher on the bullet than most others that I have used, thus, the base sits deeper in the case. My favorite .357 mag loads (used for 20 years, warm but not hot) got too hot when I switched to XTPs. The model 28 would not handle them (primer setting back and cratering to the point of dragging). Had to shoot them in the Blackhawk. Now I always reduce powder charges more than usual (in any caliber) when switching to XTPs, then work up a new load.
