Re: .........bear story from wy please share yours....
No disrespect intended - to anyone - but the only way I can fathom that 8 rounds would bounce off a black bear at close range from a 40 S&W is if the loads were completely defective (under-powered) or the bullets were designed to splat like bread dough on impact. And even the under-powered possibility is a brain teaser because the action on the semi-auto wouldn't operate if the loads were that under-powered. And revolvers don't hold 8 rounds so it had to have been a semi-auto.
I personally wouldn't spend a lot of time trying to sort this one out, because you won't find anyone else that ever experienced this. It would be like lightening striking in the same location twice in the flatlands with no trees or structures extending above ground being present. It makes for good reading, but it may have never even struck in the first place.
Even a 22 short would penetrate a bear's hide at close range - from any position on a perpendicular-to-the-bear hit. Any bullet that will penetrate the side of a 55-gallon drum will at least penetrate the hide of a bear at close range. Maybe not much more than that - but they will get through the hide.
PS: Maybe the story has changed over the years and the bear was never even skinned? Stories do have a way of evolving over the years, even without any intentions.
