Put it in a stew or something else with a heavily-seasoned sauce and you can cover a lot of the meat taste. When I was young, we'd often harvest some pretty gamey mule deer bucks and that's how Mom and Grandma used to make it edible.
An ice-cold brine for a couple of three days pulls the adrenaline and testosterone and other nasties out of the meat.
Drain and refill every 12-24 hours until water is clear.
I brine everything from fish to wild hogs/deer. It works.
