Bought a #8 that is rated for 7lb/min. They recommend a coarse grind then fine for burger and sausage. You would be lucky to get one 1/2 pound through grinder doing that.The most efficient way iv come up with after many deer is run venison and pork through 3 hole stuffier plate. Then chill and run through medium plate. With two guys working grinder i can barely fill 1lb bag in 30 seconds. Knifes are sharp and assembled correctly. It will pull long tough chunks of venison out of your fingers at 7lb/min. The throat and auger seem to have too much clearance to efficiently grind meat. You need to use plunger to force meat out.
