It's been a while since I shot slugs out of a short shotgun with a birds head grip but I found a good push-pull technique and firm grip allowed me to make aimed shots without punching myself in the face.... training and technique is important and one needs to figure out the limitations of their strength and skill level.Can-down, I think you are spot on!!!
You summarized it nicely.
Sometimes I am wondering ... if it would not be wiser to spend all that money on a course that would teach me ... the different specie's behaviors ... and teaches me how to read a bear's body language .... and to de-escalate a situation ... or to stand my ground if needed and without having to pull the trigger ....
A black bear behaves differently than a grizzly .... and a grizzly behaves differently than a polar bear ...
And how do you know that you are facing a brown black bear .... and not a young grizzly?
Somehow, I don't think that being able to shoot a split second faster will save me if ever I am faced with the situation again .... but the knowledge of how to read a bear and evaluate the situation ... to understand what its motivation and intentions are ... and to respond accordingly .... probably would ....
I only know that my Tac-14 is much easier and convenient to carry ... and once I learned how to shoot it "instinctively" ... and without aiming ... it is fast and accurate enough .... if needed .... for me at least ...
I'm not a bear behaviour expert but I've been around plenty of black bears both in my back yard and in the bush. Just my opinion but I think animals are a lot like people when it comes to aggressive behaviour, they are generally not looking for a hard fight or a situation they feel they may not come out on top of..... unless they are desperate for some reason or protecting their young. The trick is to not surprise one by walking right in to it (specially if the river your fishing is running fast and loud, or the bush is thick and your being stealthy moving into the wind) if you do meet one up close, remain calm, acknowledge the bear, show respect and talk to it calmly and then position your self so that the bear has easy options to walk away and you also have a route to back away. If an animal senses fear or weakness it is more likely to attack, if it senses confidence and strength it is more likely to not want to engage.
Bears will bluff charge and stomp the ground while huffing and puffing etc, these are sure signs of a more aggressive bear but if you are composed enough to hold your ground and explain to the bear that you'd rather not shoot it even though you are fully prepared to if needed.... you will have the best odds of not having to shoot.
If the bear has options to go another way but starts to approach slowly or is following (stalking) you, that is also not a good sign.
I have only ever seen a few grizzly and the encounters were not up close like with the black bears and I've never seen a polar bear outside of a Zoo.
As I said I'm no expert and have never hunted or shot any bears, most of my encounters I have been unarmed with the exception of a pocket knife and I've only met 2 black bears that showed obvious signs of aggression out of the many I have encountered over the years. I will add that even though they are usually slow moving.... they move very fast when they want to and can cover rough terrain quickly when they switch gears so don't get lulled in by their generally mellow vibe....
