IIRC, it was nicknamed the tround. It was triangular in shape andthat was the propellant. That and the electronic firing Remington went over like a fart in church.Back in the 60s the old Popular Mechanics had an article about a caseless cartridge. Seeing as how the brass case is a major factor in the cost of producing ammo, one would think this would be something folks would pursue.
