What about a bean bag round... Or some other non-lethal route?
They’ll just come back.
I mentioned rounds like bangers and screamers up the thread. I suspect would be effective in an incident but they'd come back. I spooked a black bear once with a high decibel whistle while boating. Scared the *hit out of hem, literally. Didn't come back looking for garbage for at least 30 minutes. If they're preying on livestock, the only solution is killing them. And their pals will get the idea the humans aren't benign.
