This propellant is a canister form of Lovex D037.1 reloading propellant. It is similar in burn speed to ACCURATE(R) No. 7, 2400 and Blue Dot. The gas generation rate is appropriate for cartridges of the 9mm and 10mm Auto, .357 SIG, .45 Colt, .410 Shot shell, light-bullet magnum pistol loads, and other high intensity pistol cartridges. It is especially good for short barrel magnum revolvers, where complete combustion, high velocity and low muzzle flash are desired. It is also possible to achieve extremely high velocities in 9mm Luger with Major Pistol.It does contain a level of flash suppression, incorporated into the propellant.A spherical propellant, it meters through charge plates consistently and will work with high-speed loaders with very good flow. It does contain a level of flash suppressant.
