I fancy making an automatic that shoots used duracells(no shortage of ammmo ever), with interchangable barrels for AAA, AA, C, & D cells.
Are they enviro safe now that the mercury is out?
Wouldn't want to tear up the tree huggers.
When my brother was kid he and one of his pals took a gavanized fence post using M80s and D-cells...They would shoot them at barges in the Mississippi from the levee.
