Don’t worry I have no intention of melting old batteries down! I value my lungs. I was wondering about stone bullets.
Granite ground down to a ballistic shape and metal jacketed.
If we can get something with the right ballistics that is dirt cheap...
GOOD on you. -I cannot tell you how many people that I know who have TRIED recycling lead-acid batteries. NOT a good plan.
Frankly, I don’t know if STONE bullets would work or not.
(I would guess that stone/granite would damage your barrel.)
