Here is picture of a dart type 12ga slug Rob made. Body
is aluminum, it has a heavy tungsten carbide insert in the
nose. The TC in the nose is about 6 times denser than AL.
Total length is 2.35 inches, weight about 950 gr. The .75" long
insert a real tight type fit. Heat AL, put in insert, cools, locks on.
It is fairly streamlined, yet has wide meplat for penetration
in game. Flat points penetrate straighter in game.
It is hollow inside in the back, behind insert which puts the
center of gravity way up front, it should fly straight even from
a smoothbore. They are fast to make and material
less expense than copper.In pic is a copper and a brass 600
cal slugs for comparison. Dart/slug on right has insert.Ed
