Abstract

A low recoil and low bore heat gun system provides a delayed pressure release mechanism for fired propellant charges in the rear gun barrel section. The delayed pressure release of the exhaust gases causes a sonic rarefaction wave along the length of the barrel bore to arrive at the exist end of the gun barrel at a predetermined time, generally coincident with the fired projectile.
