577/450 Martini Henry Black Powder Compression Die Assembly

577/450 Martini Henry Black Powder compression plug and CH4D die body. Compressing your black powder cartridge often produces more uniform ignition & velocities. All products manufactured by CH4D are made in the USA by Americans at their Mount Vernon, Ohio plant. They also make every effort to find American made tooling and supplies when they make purchases. Unfortunately, it is not always possible to find everything in America anymore, so a small amount of the parts that go into their products are imported.
