Would a air pistol shooting steel pellets at 450fps stop a mountian lion?
having never seen a steel pellet, it might, might stop him from doing what ever it was the cat was involved in doing,but he might get inquisitive about what ever bit him and decide to further investigate, i feel at that point you will discover truth to the old sayings about leaving well enough the hell alone, curosity killed the cat , and what the hell did you do that for, as you try try to tip toe away,but if that was serious questain stand your ground and fire for the eyes ,hope fully with a repeater, my sister carries bear spray when jogging above la,and has seen several ,in 30 years of hunting colo, and nm, ive seen only two but crossed tracks dozens of times
