why not load the jets? they are my favorite gun to play with.personall i would keep the older peters ammo, and the metal point super-X. the rest is not valuable beyond the worth of factory ammo. keep anything that says jet on it. if you an experienced reloader, the jets load just like rilfe cartridges,but you must be mindful of powder selection and amounts. btw, only .222or .223 diameter bullets in the jet.
