Hello All!
The 22-250, and all the other high steppers can certainly put a hog down given proper shot placement. But as is usually the case, field conditions may prevent one from putting the pill where it belongs, namely, in the ear and through the brain.
So just to clarify, the 22 centerfires can be used, albeit under limited conditions. There are new projectiles that have come out recently that have thicker jackets, more weight retention, and promise better performance on bigger game, but the implication is they are designed with deer in mind. Hog is a whole 'nother proposition.
Having said all that, I have killed more hogs with a 22 rimfire than everything else combined. And just in case anyone's wondering, I have never lost a head of game to date. I am very careful of how I shoot and when I pull the trigger.
If y'all are interested I would appreciate if you took a look at an article I wrote some time ago on caliber choice for hog hunting:
Boar Hunting Calibers. Take a look and tell me what you think.
