Now I know what you all say, but I had to try it. I was stuffing ground meat into 19mm collagen casings using the smaller tube and the speed auger. It does work. It took a while to get the hang of things but in the end I was stuffing at the rate of 5 minutes per pound of meat. Now I don't know how that compares to a dedicated stuffer, but I didn't think it was too bad.
Clean up was a different story. There was a LOT of meat still in the machine, I did do the bread trick but should have used about half a loaf instead of just one slice.
