I completely agree about the specialized pig cartridges being a marketing tool since, as everyone has noted, they can be killed with just about anything. Eons ago, the very first pig that I killed was with a load of no. 7.5 lead out of a twenty gauge. I jumped him while bird hunting and shot him just behind the ear at about fifteen feet. The only caveat about factory loads marketed as "pig loads" is that these loads are probably more popular in places like California than in Texas or Florida for the simple reason that all of these loads seem to use bullets of mono construction, and in lead-banned areas they fit the bill.

"An archer sees how far he can be from a target and still hit it, a bowhunter sees how close he can get before he shoots." It is certainly easy to use that same line of thinking with firearms. -- Unknown
