I have found the XTPs can shed jackets but dead is dead right? With 44 Mag and 45 Colt carbines have never had an XTP fail to make a massive wound channel and pass through deer and small"ish" pigs. Yes I have found jackets and jacket pieces but again - dead is dead.

If you are worried about penetration, go for some Nosler partitions or hard cast lead (I use hard cast Keith bullets in both 44 mag and 45 Colt now - a hole that big punched through the vitals does em in quick and casting bullets with my buddies is an excuse to get together, BS and pretend we are saving money).
