I have never been a "big" game hunter, preferring small game instead, but I must confess to harboring a secret desire to go after a hog. I doubt I ever will, seeing as how there aren't any around here, but the idea certainly appeals to me. I wouldn't kill it if I couldn't eat it, so I guess that would mean a smaller animal for me.

What caliber is needed to reliably put one down?

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
