All is fair in the war on hogs. Have you ever caught a deer with a snare??
I did once, and sure regretted it.
I was snaring coyotes and double damned checked tracks all over to make sure deer weren't using that slide. Slide was only about 6" deep under a net wire fence. Ran the traps and snares and sure enough there was a yearling dead in the snare.
Started using deer proof snares in slides where deer could get in them after that.
