I find home processing to be a acquired skill and set of tools gathered over time. I have done it with next to nothing and something things I have now I wouldn't do without.
Meat lugs and a basement fridge - I can fit an entire deer boned out into two of these meat lugs. A nice buck is a stretch compared to a doe, but it normally fits. I put the fish, back strap and rear muscle groups into one lug. Boned out front shoulders, neck meat and shanks in the other. I grind or can the shanks. I like these as I can rest the meat a couple days in the fridge, let it drain some. Pull it out and trim and vac seal or what ever I want to do and if I don;t finish, back in the fridge until tomorrow night.
I am picky as hell on trimming deer meat. You are chasing mule deer and they are probably lean. Our eastern deer are fat as pigs in some places. Does with 1/2" of fat on the rump and my buck from last year with 3/4" on top. Deer fat out here carries the gamey taste and is just unpalatable to eat. It has a different consistancy and just feels like it greases your mouth. A little tendon in the grind or canning, no big deal, but fat, oh no! Deer ribs here have a meat skin between the bones, 1/8" or more of fat over it, a layer of flank meat and 1/8" or more of fat over it under the skin. It is god aweful trying to get that small piece of flank meat out. Many times I'll fry it for the dogs and be done with it.
Ground medium once is fine for me. I do fine for brats, but not for summer sausage. That might be a personal preference. But I also use a mechanical mixer with my LEM 12 so I get a better protien extraction that you will hand mixing. If that is the case fine might work better for you.
On another note, I shot one deer with Hornady SST rounds in 30-06 and swore I'd never shoot another one in anything I am eating. I hit the front shoulder and destroyed all meat with in 1.5" on each side of that hole. the bullet went into the heart and opened it like a flower and the round never exited and I could not find it in the lung area. Too much destroyed meat and too much expanding lead in my food for my liking. Now I have gone to all lead flat meplat rounds in the 30-30 and probably a small meplat to almost semi spire point for the 30-06 for hand casting and loading. I got to work up the 30-06 round this spring.
