My son has used the 80gr TTSX in the 25-06 for a couple caribou bulls, a huge-bodied bull moose, a mountain goat, a couple Sitka blacktails, and a brown bear...
Was the bear a target of opportunity? I've not heard of any people hunting brown bear intentionally with a .25-06 and 80 grain bullets before. Your boy is obviously confident in his rifle choice or has a really large pair of stones!
