I hunted with the Ballistic Tips for years and never had a single problem with them despite all the horror stories I' ve heard about them. Always had complete pass throughs and never had a deer go more than 75 yards with the same results as tabbysaid. Looked like the enternals had been run through a blender. Last year I switched to the Hornady SST' s because the guy that was loading the ballistic tips for me sold all of his equipment and I couldn' t find a factory loaded BT that would group. I gave the Hornady Custom SST' s a try and the groups were right there with the handloads. So far I' ve only killed one deer with the SST' s and the performance was just as good as the BT' s. By the way, I' m shooting a .270 Remington.
