I grew up on range feed beef that had no fat on it . If we feed it grain that we raised it cut into our profits. I remember going out late in the fall when it got cold and shooting a big dry cow and hanging it for a couple of weeks then cutting it up into steaks,roasts and burger. Grandma canned a good amount in the pressure cooker and put it in the root cellar for next summer. Every cut was tougher than shoe leather. The burger was good but very dry and got mixed with ground pork that we raised. The canned beef was to die for when used in a stew or with noodles. If I had the chance to go on this type of hunt I would in a heart beat , pressure can a bunch,make sausage.
Cut some into cubes for stir fry. I'd buy some pork butts and grind it with the beef 70% beef to 30%pork for burger and the sausage. You can buy the seasonings at Amazon, sportsman warehouse etc. Better than a old mule deer in the rut that got gut shot and got hung in camp for a few days.
