That bullet has been killing deer in a MMP green sabot for about 25 years now. You will have to ask Del (SABOTMAKER) for sure, but I think that was the first sabot at MMP, and that bullet has probably killed more deer out of that sabot than any other.
You do your part, and the bullet will do it's part. I personally think there are better bullets available today, but the 240 gr XTP is very capable.
