HELP! I'm having major problems getting my Ballistic Tip bullets to open up on impact. I killed a deer two weeks ago and the bullet passed through without exploding. I thought it might have been a fluke, but I shot another deer yesterday evening and we tracked it for 300 yards until we came to the river where we couldn't continue to look. My questions is...Has anyone had a situation where a ballistic tip isn't exploding? And ..How do I make sure that my guess is correct? I don't want to wound animals...I hunt for food and can't stand the thought of not recovering the game I harvest. Any help would be greatly appreciated.
