The reported results I got are from actual kills on hogs. From 100 pounders to 150 pounders. Shots included were neck, head, heart, and lung. All hogs reported had decimating internal damage. The neck shots were reported as near 2.5 inches of the spinal column was obliterated. Both head shots reported as "blown apart". Heart shot reported as the heart was in pieces. Lungs reported as "gooy mess". The most interesting report was the fact that there was very little meat damage on entrance and exit. Now, these reports aren't from a muzzle loader but from a .458 SOCOM with rounds I loaded up with 305 grain Lehigh XP's. NOT the 300 grain ones that are actually designed for the SOCOM. These have a little bit more meplat. The 300's designed for the SOCOM have a bit more angle in the nose for better feeding which makes the meplat a bit smaller. I had no problems with these feeding but they might jam in a full auto SOCOM. Or maybe even under fast fire conditions with a semi. But the fairly strict conditions that these 305's are being used under have offered no jamming problems. The longest shot he said was taken by him was just over 100 yards and all have been pass throughs. No bullet recovered.
From what Thomas is telling me, the Lehigh XP bullet is probably the best bullet I have seen so far for hogs. That is if you care about meat damage in hogs. We kill 2 birds with one stone. Most of the hogs we take, the meat is donated to Hunters Feeding The Hungry program around the country. The other stone is of course the fight against hog overpopulation.
