Sure, Shoemaker might be the one guy in 100, or even one in a 1000, that is not only cool under pressure, but also a deadly shot.
The rest of us aren't.
When I got charged, I wasn't exactly calm, but didn't freak out either.
Bears had been on my mind every since I moved to Montana in '84, and before that when I was stationed in Alaska.
A charge happens so fast it can be over before you can react, much less get a shot off.
While I wasn't shaking while the charge was under way, I still had doubts about hitting a grapefruit sized brain while it was moving.
All bear encounters are different, because all bears act different, and the circumstances around each encounter are different as well.
There's not a playbook to go by, where if you just do "this" you'll be O.K.
Some of it is common sense. Hang up your food supply, stay away from a mother with cubs, and if you go back to retrieve a kill in Grizzly country, take several friend's with big rifles or shotguns with slugs, because a bear will have likely found your kill.
So you can't say, for instance, because Shoemaker did o.k. that you will too.
Defending yourself with "only" a handgun against a bear charge is not the same as stalking/hunting with a handgun, and you guys should know that. You blink, and the attack is over.
I met a guy who lived in Las Vegas once who'd shot a world record archery elk the year before.
We got to talking about bowhunting, and he showed me some claw marks on his ribs.
He was hunting on the Alaska coast for Sitka deer a few years earlier, and was walking around a huge boulder on the beach. As he came around it, there was a big Brownie. I'm sure both were surprised.
The guy only had time to get his .44 out of the shoulder holster enough to touch one off in front of the bear's face. The blast and noise was enough to send the bear away, but had he wounded it, even an eventually fatal wound, he would not have got off with just claws across his ribs.
