I've made sausage once, combining some feral hog and venison. It turned out okay, but not really all that special. So, I haven't made any in the past couple of years. I trim off as much fat as I can from the hogs, and only grind the meat if it's too tough for other use.

Having said that, even a boar the size of the one SWT recently shot makes good ground meat. I usually cook it in something that has a sauce, like spaghetti, but I've also used the meat to make hamburgers which I grilled, and they were quite good.
