Shooters World AR Plus D073-04 Smokeless Gun Powder is a bulk form of Lovex D073.4 reloading propellant. It is similar in burn speed to Accurate 2230. The propellant gas generation rate is appropriate for cartridges of the light to moderate sectional density .223 Remington and .308 Winchester cartridges. It costs slightly more to run this propellant in the above cartridges than D073-01. It does contain a level of flash suppression, incorporated into the propellant. A spherical propellant, it meters through charge plates consistently and will work in a high-speed loader with very good flow. 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. 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
