I like the idea of one person armed with spray and the other with a sidearm.
“If you don’t hit the bear in the right place guns don’t work either.”
True...I’ve heard lots of stories of bullets hitting a grizzly skull at a shallow angle and ricocheting off. I hear that angers the bear.
I hear shot placement with a rifle or pistol gets a bit tough when a bear is charging you and is 15 feet away. You get one chance.
Actually firearms work very well.
