At high impact velocities into tough tissue or bone the BTs tend to blow into long shards. Those shards can radiate from zone of maximum dynamic pressure within wound channel at near 90' angles. That is actually nothing new! Been known to do that since the Nosler Solid Base came out a lotta years ago!!! (same bullet as the BT except for the plastic tip on the BT). Both the BT and Solid Base are nothing more than conventional cup core bullets with thick base cup and a semi boat tail. Will they kill stuff?- yes. Are they generally an accurate bullet?-yes. Are they the best bullet choice for serious hunting, expensive hunting trips, critters that deserve the best humane kill?- no IMO. Targets and small per caliber varmints?- fine. Penny wise, pound foolish. Can you take most any bullet and run it at high velocity out the end of a barrel and kill something?- yes.
