Ballistic results for Shooters World Blackout D063-02 Smokeless Gun Powder show it appropriate for both pistol and rifle cartridges that incorporate a near straight-walled cartridgecase. The propellant gas generation rate is appropriate for .300 Blackout, 7.62×39, .30-30, .22 Hornet, as well as many lever-action pistol and rifle cartridges where rapid transformation from powder to gas is desired. It is similar in burn speed to Accurate 1680. This propellant is optimized for a broad range of heavy bullets for .300 Blackout, subsonic. Especially appropriate for 200+ grain bullets, the combination of charge weight, geometry and chemistry provide assurances of cycling in AR platforms. Despite its optimization for heavy bullets, it can launch lighter supersonic bullets in the .300 Blackout. However, loaders generally find superior results with supersonic projectiles, using SOCOM. A spherical propellant, it meters through charge plates consistently and will flow well in a high-speed loader. It contains a level of flash suppression, incorporated into the propellant. Another advantage to Shooters World propellants is the long track record of these propellants. The Shooter’s World manufacturer has been making propellants since 1920. Many of these propellants are sold throughout Europe under the Lovex brand. The density of Blackout is approximately 1 gram/cc. It contains a level of flash suppressant. Its spherical geometry assures highly consistent powder drops when making rounds on a progressive loader. Under the Lovex brand, this propellant is referred to as D063.  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
