Grampa used to call em "bean flips". That brings back great memories as we would walk all over creation with a pocket full of gravel and one "in the chamber." Pestered every living thing that didnt scoot when we eyed it. Even killed a rabbit once, though I can't tell you how (gravel tends to go every way but straight.) As I grew older, we would use .36 lead balls and our consistency improved greatly. With good ammo, it wouldnt be hard to knock a bird outta the tree... Gives me an idea for the next elk hunt. Thanks Joe!!
