interesting. For about 15 years I used to hunt exclusively with nosler ballistic tips and often experienced that same result (the bullet exploding into shrapnel); in fact they would sometimes start to come apart when going through light brush. So as the area I hunted began to get thicker due to logging, I eventually stopped using the BT's and tried the accubond. But only once - my only experience with that was a 200 yard shot, a 300 win mag/150gr accubond that went through the ribcage, seemingly without opening at all. There was a minimal blood trail and I was lucky to find the deer 100 yards downhill thanks to the snow. So I figured the BT was too frangible and the AB was too tough, and I switched brands all together.
After that I tried and stuck with the Barnes bullets for any kind of hunting in thick areas. I've killed quite a few buck now with that bullet in various calibers, and have not experienced any failures. Most open up nicely and leave a decent exit wound, but the last one I shot hit the off shoulder and I recovered it, nicely mushroomed.
For doe I still use the BT's though, as I usually hunt them over open fields.
