Ballistic tip bullets are killing bullets for sure. You may be certain of rapid expansion, full penetration, and a gruesome wound channel. If you shoot the "eating parts" you will be sad, I promise. However, if you take a brief moment to ponder the shot before you pull the trigger to consider that wound channel, and then place your bullet well, it is for sure that your deer will be dead quickly, just as it should be. They are great, dependable bullets.
