Right guys....shot is definitely the handy way to go. Another alternative ...granted less handy...is solder lead available at hardware stores. Runs about $15 for a 5Lb ingot. BTW, the local tire shops have an agreement with a fellow to sell him all their scrap tire weights: I'm guessing the reloaders are having an equally tough time getting material for ammunition.
Hummmmm, I wonder if the gun range run me off if I showed up with a shovel???
