Brian Pearce wrote an article on 357 levers. Rifle 213.

Spoke of an incident, 140gr. SWC cast SAECO at 2,000 mv. owner had a Browning 92 converted to 357, had a sow black bear charge close range and killed it at a few feet instantly, bears momentum knocked down the guy, but he was ok. Combo worked.

No info on shot placement, or how many rounds, one or more.

Just thought I'd pass it on.
