As a matter of fact, I have looked very closely at the "structure" of a hog's body, having been lucky(??) enough to have assisted in the caping & skinning of at least 5 different hogs of 225 pounds up to 450+. Four of those hogs were boars and we have taken numerous other hogs up to 200+/-.

If you'd reread my posts, you'll see that I did not "fault the caliber". I merely stated my experience(s) in as plain English as I can. Take them for what you want or discount them, I really do not care. I just know that in our experiences with free ranging Georgia hogs, we've learned a good deal about how and what to use to kill large hogs.

I read a lot of comments about how easy it is to kill "any" hog with a shot at/near the ear. Typically with most hogs, that is an excellent choice and will normally work just fine. However, hogs do not typically "pose" as deer will. They are normally always moving, even while eating. I would suggest that on a really big boar, you do your homework and understand what killing one might take; no more, no less. Shown are the shields of a couple of boars 225 & 260 pounds. We failed to get a picture of the thickest shield we encountered, unfortunately, and it was double the thickness of these two. Easily equal to both these together.

A sow still carries the musculature of a hog, and it can be substantial in a 250-300 pound specimen (we've killed some of those too). But whereas there is ZERO shield present in a sow, killing one is much easier to do. Not everyone who hunts/kills hogs understands that, IMHO. To be under-gunned when pursuing big hogs seems silly to me. The owner of the place where we hunt in Georgia agrees, especially when he shows you the collection of skulls from hogs ultimately found dead, that ran off after a shot that took too long to take effect.
