Bear bones are considerably softer and less massive than say moose bone. They are incredible tough, but not not so that a bullet would notice.
I have sent quite a large number of 270gr Barnes through brown bears, mostly Kodiaks, and have never recovered a single bullet, including a number that went lengthwise through extremely big bears.
I like the old XLCs, but had to switch to TSX when I ran out.
270 is not gay in this case...
