Sorry but this makes no sense whatsoever. I'm not sure what logic is used to come to this conclusion but it is diametrically opposed to conventional wisdom regarding dangerous game. When hunting, the critter is calm and caught unaware when the bullet strikes its target. They also typically don't know where it came from but their instinct is usually to run away, which means that by the time you see them again, they have bled out. On the flipside, a critter that has decided to go on the offensive is enraged and charged with adrenaline. It knows where you are, it knows what you are and it wants to kill you. It takes MORE to stop them, not less. This is why bolt action rifles are often used for hunting dangerous game but a double rifle is chosen for the approach or any other time a charge is imminent. Charges are stopped with big bore double rifles, not AK47's. Same logic applies to handguns. If I was hunting brown bear, I might choose a .44Mag as my primary but carry a .500 as backup. I would at the very least choose the same cartridge and the same load, using a platform more conducive to speed as my backup. Because when things go south, I want the greatest terminal effect I can put on target with each shot. This idea that the cumulative effect of a 15rd 10mm is as effective or more effective has no basis in reality. High capacity 10mm's need not apply.
