Bear ate that bullet and kept on charging. Which gun would stop that bear in one shot?

45-70 gov

This one.

Lever action 45-70

Not many, especially a charging bear. Double, especially a large charging bear. Interesting fact. In 100 years of attacks, 9mm was the caliber that was mostly used to kill a bear mid attack if memory serves, next was 45, and I believe 40. In one shot, the placement is key. And a jacked up bear is not likely to be dropped in one shot. Family members of mine have taken bears in one shot with 30 30. But they were clean and surprise shots.

I carry a G20 10mm but luckily the bears are very skittish on my property. They’ll watch from a distance but even the sow with cubs runs away lol.
