I recieved a LEM Jerky gun for X-Mas. A couple ?s The gun came with a packet of Jerky seasoning and a packet of Snack Stick seasoning. That is the differemce between the two products, Jerky and Snack sticks? Seems like they could be very simular in the fact of using the same meat and possibly very simular seasoning. If these assumptions are correct them why do we have both? Does Snack Sticks have casing? if so what size? Are Snack Stick basically like Slim Jims you can purchase in the store?
