Some of the much larger hogs/boars arent worth keeping because they can be really tough but otherwise if you quarter them up, get them on ice you should be good to go. Bleeding them out on ice can easily remove any game taste you might get.

I am so used to eating wild game that it rarely tastes gamey to me.

Another trick is soaking the meat in milk & egg mixture for a little while before cooking it...that definitely helps too...
