I use the LEM Jerky Cannon, it works great. Also have the original Jerky Shooter and NESCO Jerky Works. Only use the Jerky Cannon anymore, its aluminum and holds a pound of meat. I use the round tip, and make up a pound of sticks as I need them. I think they taste better that way. Getting ready to make a batch up here shortly, that I mixed yesterday.
x 3 on the LEM jerky cannon I use the dbl jerky tip and I love it ! I make about 120 lbs of goose jerky every year out of it !!
Just remember if you add water to if your stuff will take a lot longer to dry and its a bit messier ! I have been making this amount of jerky every year for the past 20 + years and I still have the same gun !
