Kawshik,Co Elk Hunter ,
You are correct that shot of any size is inappropriate for large animals. However , l have killed Indian Bears with SG cartridge from my Ishapore shot-gun fifty years ago. You see , the bear is an odd creature. It's head structure makes it close to impossible to secure a shot to the brain as their brain is very small. At distances of 5 or 6 yards , the aforementioned SG shot treated with bees wax can work excellently on a charging bear from the front position. The method is to keep your calmness until the animal is at close quarters . 7 yards or less is ideal. Then the shooter fires at the head of the bear. The concentrated charge of large shot at short distance is very effective for finding the brain of a bear.
I have a photograph of such an incident from 1966 , of a bear killed by myself which had attempted to charge at a client.
Perhaps it may interest you ?
However , just because something can be done , does not mean that it should be done and magnum .300 by Winchester would be a much better tool for this application.
Almost everything here on AH interests me! Your information, stories and expertise included! A grizzly bears skull is much thicker than other bears. I have a 10mm Glock that I carry in the words here in Colorado for protection against a rogue black bear or mountain lion and load it with 220gr hard cast bullets. But, just as with buckshot, I wouldn’t carry it for protection in grizzly country. I WOULD carry a .454 Casull or larger handgun though.
