I have had the same problems with ballistic tips. At close range driving them at high speed they will act like varmint bullets damage a lot of meat. But at long range were the bullet has slowed they make some of the best looking mushrooms.
Were I hunt you may get shots at 30 yards up to 1000 if youare will to shoot that far. I have switched to the bonded bullets. I think they are a lot better than the Ballistic tips in my hunting situations.
This Interbond was fired at above 3400 fps @ 90 yards into a 300 lb whitetail retaining 115 grains of 154.
My son recovered a 150 Ballistic tip this year and it was 33 grains. Only thing left was the jacket and the deer had massive damage detroying both shoulders.
Here is a pic of the Interbond and I can find the BT to take a picture. I will see him later today to get it.
