This I believe could be misleading/misinforming.....a hunting ballistic tip (or similar) is constructed just fine, we'll save anecdotes for later but ballistic tips do work. Nosler themselves warn that using a ballistic tip under 50 yds is not recommended. They will still kill deer at distance. Fire one into ANYTHING at mv and you have a high velocity grenade that may or may not penetrate enough to kill depending on circumstances. With the .270 in particular, I got to watch a friend test the new BXR 134 gr on a frontal chest shot on a decent corn and alfalfa fattened whitetail doe at approximately 20-30 yds. THESE ARE DESTRUCTIVE. The bullet entered midway down in her chest at a slight downhill angle. Upon immediate contact it was like what the Glaser safety slugs are supposed to do. There was less of a wound channel entrance/exit scenario, and more of shock wave of vaporization. There was damage from the top of her neckline to her brisket, separation of an entire shoulder and holes on each side of ribs. She still ran dead on her feet for another 30ish yds. As my friend said "I'm used to having 100+ shots, that's why I bought these!!" Based on the actual penetration, I would never trust these to penetrate heavy bone and any broadside or quartering away shots should still be placed forward of the diaphragm at close range. Velocity will always be the enemy of a bullet designed for expansion at distance. This doesn't mean that they are not constructed properly, only that high velocity cartridges need paired with harder bullets at close range. If not, there would be no market for partitions and mono metals established before lead free zones. Even a 150 cup and core would have behaved differently at that distance. My wife's .243 at 50 yds with 100 prohunters created a similar entrance scenario but penetrated much farther, I don't think either bullet/load combo failed at all as we were plenty busy butchering, but <50 is not where I would call ideal on a long range rapid expansion load. Only bonded and partition loads seem to fill both needs and yet deer are taken at all ranges with everything from .223 vmax to .338 tsx (and larger).
