I've watched incredibly talented pistol shots absolutely Fall Apart when we towed a life like bear Target towards them.. cops, combat vets, etc. Think the multi tour combat vet got it on the paw on the first go, I've towed the darn thing at near 50 people over the years when we had the towable one, only had a couple rifle guys make a vital hit on first try. Kinda funny since it's a plywood painted bear accelerated by a small car....
Granted a hunted bear is not a charging bear, but the conversion can be pretty quick.
Once towed two long track mountain sleds across the west with an aluminum 2x place trailer and a Honda civic hatchback. Can be done, but when speaking in general terms I'd reccomend something better suited. Same goes for the big bears, talented individual is probably good to go. Average dude should probably step up to a bigger bore rifle and practice.
Seeing a few early sign of bears coming out, wonder what the over under is on first attack of the year. My money is on hippy dippy running in spandex, since last year was servicemen on base....
