With all due respect, if bear is charging, and you deploy flash bang 20-30 yards away from you, with no success... it is game over!
Fact: Bears can run more than 60 kilometers an hour, and they can do it up hills, down hills or along a slope. To put that in perspective, that's 15 m/sec or 50 ft/sec, more than twice as fast as we can run. In fact, a bear can outrun a racehorse over short distances but has little endurance.
That would mean that you will throw flash bang, observe it fail to affect bear's full speed ahead charge, and will have less than a second to pick up firearm (load it or take off safety), aim it and acquire target, and of course shoot accurately at the fast moving bear.
On the other hand flash bang might work on a bear that is fairly passive and approaching slowly.

So all we need now is an underbarrel flashbang launcher, or a muzzle-mounted discharger cup...
