Dave that is really good. Even better than the 300 gr XTPs. I have some of them 200 gr .40 XTPS that I shoot out of my 45 Renegade. Now I just may have to try them in my Genesis. Guess I will have to order a pack of those MMP sabots. (you have a part number for them?)
I have no doubt that that combo will take a deer. You should have plenty of punch with them.
