Sabotloader, I've only recovered a couple of XTP's over the years. Haven't really used them a whole lot either since I only own one smoker that will shoot a sabot. But the couple I have recovered held up nicely. No jacket separation and no blowing apart. But I didn't push them really hard either out of that renegade. 80-90gr Swiss FFG. 80gr with the 250gr and 90 with the 300gr. I know, seems backwards but that's the way that rifle likes it. The heavier 300 likes a little hotter load to tighten the group.
