ok so no round is big enough when it comes to defense against grizzlies... aside from a 500 magnum and a 50BMG. I did a little research not too long ago and put an order in for 10mm incendiary (explosive) rounds for my glock. they came in and they make a pretty damn big "explosion". Look on youtube you can find a few links demonstrating their effect.

Bottom line, I know these rounds wont explode unless they hit a hard surface (metal, concrete, bear skull etc). do any of you think it would be decent defense against a charging bear? theyre made to start fires, maybe it can set the bear on fire? burn its eyes out? do NOTHING? looking for some input, thanks
