Have to disagree with you there for sure.....even the bestest most awesomess "boolit" doesn't means squat if shot placement isn't there regardless if there is "luxury" of time to placement or not.
And just because some guys with lots of time behind a big bore handgun can make them dance doesn't translate to most of us mere mortals.
I realize you put a LOT of time and energy into becoming proficient with a handgun and likely shoot a 1000 plus rounds a year to maintain the proficiency. Much like member Fjelljeger does with his handgun.
Reality in a charge no one is thinking of getting off 3 shots with a rifle....or even a handgun. Its all about what you can best place a shot in a moment of panic.
But I digress I really don't know why I get sucked into these conversations and reality is no one in this thread will likely ever need to use a weapon on a charging bear that hasn't already been hit in the act of hunting it. In that case you'll likely already have your rifle at the ready anyways as I don't know a single guide that ditches their rifle to get out their handgun as they go into the alders after a bear.
