Yeah - I can imagine the fun, testing different powder charges, different lubes and patch thicknesses - hundreds and hundreds of shots -

ouch! Instead of stealing the weights off cars, I'd go for the tri-drivers and trailer locking trucks - heavier weights. I figure you'd get enough from one logging truck lets see, 26 tires, probably 36oz.(3 pounds) of weights so you could cast 6 balls

. Hmmmm - need a better source of lead!
