Well, i think i strongly agree..................i think. The Nosler does indeed penetrate deeper. The Nosler seems to have caused massive amounts of 'shock', when one examines dead critter.

The photo shows a pile of bullet that were found on the hillside behind the target where i usually shoot. Deep Curl on the left. Nosler on the right. Only 2 Nosler; don't shoot them much, especially at paper. No XTP shown, but every XTP i have found has been found in pieces, with the lead separated from the jacket.
