IMO that's pure unadulterated BS. If a Barnes hits a deer like creature at 320 yards (the OP's max range estimate)chances are pretty slim that it won't exit. That being the case, how in hell does the OP come to the conclusion that NONE of the bullets expanded beyond 25%???
I would be willing to bet that this is one of those cases of looking at the hole in the hide and leaping to conclusions. I cannot imagine how many hundred deer a person would have to shoot to recover enough Barnes bullets to have an informed opinion of their expansion from recovered bullets alone. I have examined quite a few deer shot with Barnes and about all I can figure is that they wreck stuff on the way through in a manner consistent with expansion and appear to cavitate through the chest very well. Out of about sixty deer I have yet to see any evidence of failure to expand.
