But you would still get better penetration using a 180 gr Barnes x,Tsx or MRX.I wasn't taking anything away from Barnes they make good solid bullets.
I have yet to find a NP to weigh after I have fired it into a game animal,they generaly keep going after impact.I have found lesser ones like core-loks 180's,Federal Classic Sp 180's and Winchester PP 180's and they weigh about 40-60% after impact.
