9mm vs 10mm for Bear defense.

I didn't watch - whatever you shoot best is what you should carry.

This is the correct answer.

I’m confused by what you’re saying here. I totally agree in principal…double lung a bear and they stop quick. At least that’s been my experiences and what I’ve observed.

But….to double lung black bears I aim nearly middle of the middle. That same shot would gut shoot a deer. A perfect shoulder crease shot on deer could miss the bears lungs.

Deer have larger lungs proportionally to their bodies and hearts that are farther 'back' than bears do.
