Yes - that was a javelina. I used to throw ‘chicken scratch’ out for them at the same time every night. (They have built in clocks, btw).
Then, one evening, the boar, tried to break into my closed in porch when he didn’t get a refill, when he wanted it.
That scared me - and I decided to quit ‘feeding’ them.
I have a 350 S & W - with laser point. But, if anyone from the Fish and Game ever found out I killed one of the little buggars, I’d end up in jail for a long time.
BTW, there is NOTHING to repel them. I had a ‘family’ of 11 that came here every day, and teared up my property. I had the Fish and Game Dept. come out and tell me what I could do.
They told me ‘nothing’, except quit feeding the birds.
I had bought a b-b gun - (spring loaded) thinking it would deter them - but the shots didn’t phase them. (Their hide is two inches thick, I think.)
I bought a wrist sling-shot with steel balls - but, didn’t like the thought of injuring an animal. (The steel balls I shot would shatter large rocks.)
So - I just put up with them - as they tear up my place. Yes - Arizona. How’d ya guess?
As close as that small pig was, I'd say a .357 would do it. Maybe even just a .38, but shot placement is critical. But I don't use such a light caliber (except for once).
I've taken a hog up close with a handgun...if one can hit the base of the skull right behind the ear, that drops 'em like a rock.
