I'm surprised that the accubonds tore them up. How was your shot placements? Sierra doesn't make a 110 for .257 but they make 100, 117, and 120 gr. plus some smaller ones. I have used quite a few different loads for antelope and none didn't really seem to do a lot of damage. It seems I usually ruin one front shoulder, but my favorite meat is the back straps and hind quarters anyways. My favorite is 100 gr. nosler ballistic tips in the 25-06. Maybe the sierra bullet he was shooting held together better, and maybe they were flying a little slower? I would think a slower bullet wouldn't do as much damage? I wonder if a solid copper bullet would work well where it might just poke a hole through the animal.
