The NABLR expands at long range at slower speeds to give mushroom but still penetrate. They are however bonded and very solid even at close range retaining about 58% bullet weight at 100 yds, still holding together and retaining bullet weight at 7-800 yds. What they don't do is penetrate about 2 inches then disintegrate as Bergers are designed to do. Watch their video. Some love it, I don't. If you hit the shoulder or other hard bone on a big critter with an explosive bullet you often fail to penetrate at all and just create an ugly surface wound. In 50 years of global hunting, I have never seen a Nosler bullet fail or experience a core jacket separation, thought I have with Hornady, Speer and some Sierra...sometimes it happens. The 143 Norma Bond Strike gives similar performance and I love me some Barnes TSSX in these warm mid-caliber cartridges. I have never used Hammers but I'm intentionally gonna load up some 6.5 PRC, 6.8 Western and 7mm-08 just to see if I experience the white light surrounding me everyone else does by using this bullet
