I can't be the first person to think of this: Instead of using the orange skeets that leave ugly residue at the shooting pits, for target practice I have used the inexpensive flat dried tortillas for targets. They are found in the supermarket ethnic section, about a dollar per dozen. They shatter when shot, and are self-cleaning with the nightly assistance of coyotes and wood rats. No ugly orange litter. Keep a bag or two in the rig; at worst they can be survival food too!
