SHOTGUN CARTRIDGES

Easy, JK6 isn?t actually the name of these cartridges but the propellant, instead.
This means any cartridge maker can stamp the name on a case if he chooses to fill it with that particular powder.
This particular propellant forms part of a range made by Bofors in Sweden.
Because of its burning characteristics it?s one that loaders like to use in heavier load cartridges for, say, high pheasants.
