RE: Ballistic Tips
I have been reloading 165 gr. Nosler ballastic tips for my '06 for about 12 yrs. now. I have yet to hit a deer and not find it shortly. I can honestly say that the very few deer that I have had to track from point of impact were pass throughs. It was like rolling out the red carpet.
One thing you may want to consider is those magnum loads are traveling so fast that the shattering and deflection effect is multiplied. I have a buddy that had similar problems with a 270 mag with 130 gr. ballastic tips.
