I’ve shot quite a few with 140bt out of a 7-08 running about 2750 and I shoot’em right in the shoulders and get exit holes 90% of the time. That being said I probably wouldn’t do the same with something pushing them 3k or faster. I do shoot the accubonds in my 280 and some other faster rounds and I love them. I’ve never had a BT fragmentation on anything running under 3k, not saying it’s not possible but this is just my experience.
