I have a Nesco as well!
I don't use a jerky gun, rather, just cut the meat into 1/4" slices, marinate in a favorite marinade (I love the Allegro brands, even over homemade), usually marinade over night, and then lay in the trays, sprinkle cracked pepper over it, sometimes some garlic powder, and then dehydrate til done! It comes out sooooo yummy - DH eats pounds and pounds of it (and so do I, but he likes to scarper with it).
