This is Underwood's comparison of the 150gr Xtreme Hunter with their 180-200gr XTP for mid size game
The Xtreme Hunter series was designed with medium game class in mind. The 10mm 150gr Xtreme Hunter offers about 28" of penetration with a great volume of wounding. Comparing a 180-200gr XTP, we typically see 16-17" of penetration with the XTPs at best, so comparing with the Xtreme Hunters there's an extra 10" of penetration to work with for weird/bad angled shots and there's no need to worry about bone with the Hunters as well being a solid non-expanding bullet. The Hunters are also able to wound effectively deeper into the target as well since their damage is not focused up-front like a hollow point.
