Oh H3LL YEAH !!!Ammo is a bit pricey. I'm sure someone will come up with a way to reload the mags.
Why buy such a single use device? I just buy the cartridges and use them in my Crossman Vigilante. BB's, Pellets, Salt it will shoot them all.https://www.bugasalt.com/products/shred-er-salt-cartridges
I have not tried it yet but there are several reloading videos out there. Waterbugs and carpenter bees are particularly fun to shoot.
