ABSTRACT:
A cartridge for a powder actuated tool having a cartridge case, a powder propellant, a bushing, and a piston. The piston has a tapered outer diameter that is larger in a rear end of the piston and is compressed inward by the cartridge case. A port extends through the piston and has an entrance to the port at a rear end of the piston with a semi-spherical shape to slow gas flow rate passing through the port and reduce the amount of propellant residue passing through the port. The piston has a main section and a cantilevered section. The cantilevered section has a general ring shape and forms a portion of the outer diameter of the piston.
