Since I don't hunt I use London Broil when it is on sale. I have tried it on some Elk that was given to me and it came out great.

The marinade consists of:
3 tsp Cayane pepper
1 tbsp Liquid Smoke
5 tbsp Worchestershire sauce
5 tbsp Terriyaki Sauce
3 tsp onion powder
3 tsp garlic powder
3 tsp oregano
2 tsp pickleing salt
1 pack mesquite marinade
20 shakes tobasco sauce
1/2 cup water

This is good for 5 lbs of meat. Shake it all up and marinade over night making sure to mix thouroughly. I have three dehydrators with 12 trays each and it usually will take 20 lbs of meat to fill. I dehydrate for 8-10 hours at 145 degrees.
