This propellant is a canister form of Lovex D037.1 reloading propellant. It is similar in burn speed to ACCURATE 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. A spherical propellant, Major Pistol meters through charge plates consistently and will work with high-speed loaders with very good flow. It does contain a level of flash suppressant.Warning About Smokeless Powder: Do not exceed the loads displayed in the reloaders guideNever mix any two powders regardless of type, brand, or source Never substitute any smokeless powder for Black Powder or any Black Powder substitute
