Just circling back on this post. I killed a deer in November and tried several different grind types. I single ground some with the small (3/16") plate, single ground some with the medium (1/4") plate and double ground some with the large and small plate.
After cooking all three I've decided if you blindfolded me and sat them all in front of me cooked I could never tell you which was which. For what I use the meat for, which is just ground meat (no sausage, brauts, etc) I've realized I'm just wasting my time with 2 grinds and will be using the med plate and a single grind from now on.
