I usually do my own. Don't really like the taste of venison so most goes to jerky or ground. Little trick a buddy taught me on the ground. Instead of adding beef fat, go to walmart and buy one of those big 5 lb tubes of the 70/30 hamburger. It is actually about half fat as you will see when you open it up. There is enough fat to do an entire deer. I grind the deer up first then run it back through the grinder mixing in the hamburger for a second grind. Works great.
