Berger hybrids, eols, elite hunters, all have a slightly open nose, these bullets are tumbled in polishing media before packing. This medium can get into the nose packing it shut. Clean the tips on Bergers you plan to kill with, all of them. I've observed or pulled trigger on prob 40-50 kills with Bergers ranging from vldH, hybrid, eol, lrht. If the tips are clean and open with sufficient impact velocity(2000+), they'll all wreck shit.
