You could kill geese all day long with 2.75" shells and #7 shot. You'd have to alloy it with something hard enough to withstand the acceleration.
Modern computing and all that goes along with it would be impossible without gold... ask anyone that works in the industry. They mine old computer equipment... for the gold and other precious metals.
