Are feral hog hind quarters hams, or a different type of pork?
They would be fresh hams, the hindquarter of a pig.

The word ham, unmodified, implies a cured product.

I would imagine that for a feral hog, if you are willing to risk eating it, that you should cook to the highest temperature reasonable, which in the case of a fresh ham might be at least 180 F, and as high as 200 F.  The best application at these ranges would be making puiled pork, which requires long, low, and slow cooking; smoking is definitely an option.

See also this recipe, although for a pork butt, should be easily adaptable to the fresh ham, which is similar, although not quite as fatty and full of connective tissue, so it won't be quite as tender when done.
