Yeah, I was pretty amazed with the expansion of the modified XTP. I was pretty sure it would increase expansion, but I was afraid it would cause bullet failure (fragmentation, jacket separation, etc). When I weighed it next to the regular XTP I was shocked that it retained more mass. In fact, after I posted the info, I thought I might have gotten them backwards, so I weighed them again. I was right, the modified one was right at 200gr.
I'm gonna test a normal XTP in the wax tube tomorrow, and I'll do the modified one after that (probably Tuesday or Wednesday). I can't wait to see the damage it will do to the wax tube. I'm hoping it will still penetrate well. I'm expecting it to go about 12" in the wax. If so, that would be a monster hunting round.
