Finally just did it. Made a batch of snack sticks from some venison grind I'd set aside for the purpose (5lbs of grind).
I picked up a Cabela's Commercial Grade 1/2hp grinder for a decent price off Craigslist, and bought the auger kit to use it to stuff. That seems to work pretty well. There was definitely a learning curve to that process, but my oldest daughter and I worked it out, I think. :)
I ran the batch through my MES for about 8hrs, and used a LEM mix and cure on the meat with Cabela's casings (I live near a Cabela's store, so it was convenient to get their casings).
I pulled them out at an internal temp of 153 and put them in cold water (didn't have ice...used a bus tray of cold water and threw in some ice packs, but it seemed to do the job).
My daughter and I sampled a bit and they were quite good as far as moisture content, weren't gamey, and seemed just right. I think the flavor was a little on the bland side, which is the LEM kit's seasoning.
Overall, though, they came out pretty decent, and at least I have something of a start!
Thanks everyone...reading on here made this a lot simpler than I thought it would be!
