If you go with any type optics try and find something as low powered as you can with a simple illuminated dot in the center or in the center of the cross hair. If your going to use standard iron, you might want to pick up some china chip repair from the hardware store and touch up the front sight and tips of the rear. In low light, (think thick canopy, early or late) on a black hog, your iron sights will simply disappear.
The link posted above will serve you well to study up on their anatomy. I shoot plenty of them and in most cases I do my best to hit them from the leg to the ear with anything I am using. 95% of the time it will result in them hitting the ground. Some of the bigger ones might require a finishing shot, but most drop like a rock. There are times however when the lighting is poor and when they are moving along at a pretty good clip, when things simply don't always go where you thought they should. Those are the other 5%.
If your looking for the best eats, the faster they hit the ground DRT, and the faster you get them skinned and in the cooler the better the meat will be. I realize that will depend on how far your hunting back in the sticks or swamp, but it is especially important with the heat we're getting into.
Like MC stated, over here there simply isn't much we can't use or do to dispatch them. Myself and my good friend have been doing our part for a number of years to take all we can out of the environment. Even with shooting every one we can manage to acquire a sight picture on they are still winning.
As for your Max, if your loading your own, the Hornady XTP is a good jacketed, or you might consider using one of the excellent cast WFN, or RFN designs. The thing about using them is you don't actually have to push them to the top end to get great penetration or a good wound channel. If your load is accurate, and running between 1150 and 1350'ish FPS, it will do a number on a hog. Out of my 6" GP-100, I have been using some Oregon Trail 158 RFN's, and I'm loading them to around 1250fps using H-110 or 269. The hit with authority and will easily drive right on through a 150'ish pound hog. I have taken several with it, some were DRT some weren't, but the weren't was fully due to when the first round goes off, you shoot for hog and don't always hit in the specific area you were aiming. Usually when we are up in the thick stuff is when things get touchy, as you might only see one or two, but when the hammer drops you might immediately find out there was actually 8-15 or more up under the brush you didn't see.
Look over the link posted and study how they are built and you will be ahead in the game. Find something you can use in low light and still see, and remember hogs are usually black or dark in color, so you can easily loose black cross hairs or iron sights. Most any of the fiber optics, if you can find them might work out, but they still need light and I have a set on my 41 that have been too dim to see while I could easily still see the hogs. The white china chip repair enamel will shine pretty well even when it is too dark to be shooting which is why I have used it on most of my iron sights. You only need a touch. Just be sure to clean your ramp and rear blade off using some denatured alcohol and a q-tip, before applying it to remove any oil.
We're in agreement, then.
