Jonathon yep, shorter horn makes sense. I am mech. engineer and there are two big things wrong here: the 9.5mm (3/8") stuffer tube and its length. Most of the problem, probably, ALL could be solved by using the diameter stuffer tube for 16 mm casings. There is NO advantage to going smaller, just disadvantages. Pressure drop(in this case back pressure on the cylinder / piston goes up exponentially as diameter is reduced.
I am currently using a small scale jerky gun from RedHead to shoot jerky, until I can afford the equipment here. Will the sausage stuffing tubes and meat stick tube fit the RedHead or Jerky Cannon gun?
steve brown45 I am not familiar with your jerky gun but I have the LEM Jerky Cannon and the tubes from my Walton’s stuffer fit the Jerky Cannon.
steve brown45 The big issue would be the outside diameter of the back edge of the [censored]. If yours have the same diameter, which is 2 - 1/16th inch, then it should work. The Inside Diameter might possibly cause an issue as these are designed to have the force of a stuffer behind them and the RedHead might not have the same pressure but I really don’t believe it will cause an issue.
