Good video. That's exactly how I have been doing them for 20 years now and it really is as simple as he shows.
For tenderness, I have found if you have access to a cooler let the deer hang for 7-10 days and it will make a big difference. If the temp. is below 35deg it won't help and above 40 is unsafe so you really need a cooler.
The tenderloin and backstrap are obviously tender and the top,bottom, and eye of round are still tender on surprisingly big animals if you DON"T OVERCOOK them. Medium rare at the most. The sirloin tip which is the football shaped muscle he removed first on the hams is the least tender and I always grind or jerkey it. On small deer I leave the 2 upper muscles on the shoulder hole and cook them like steaks but otherwise I grind or jerkey the shoulders too.
I would never take a deer to a processor even if money is no object. There is just no comparison between the products you end up with. I can't tell you how many people that "don't eat deer" eat mine and say they can't believe how good it is. Did I mention not to overcook them?
