HS-6 is a fine spherical propellant that has wide application in pistol and shotshell.  In pistol, 9MM, 38 Super, 40 S&W and 10MM Auto are some of the cartridges where HS-6 provides top performance.  In shotshell, HS-6 yields excellent heavy field loadings in 10ga, 12ga, 20ga, and even the efficient and effective 28ga.  HS-6 is truly an outstanding spherical propellant.  HS-6 is identical to Winchester's discontinued 540.
