Shooters World SW4350 is the slowest of all the 4350 derivatives. As such, it has broad capabilities in moderate calibers where other 4350 derivatives cannot reach 100% loading density. It also has enhanced capabilities in larger magnum calibers, where other 4350 derivatives cannot reach. If you seek accuracy, one of the keys is to find a propellant that can “fill the case and seek maximum velocity”. Several shooters have found this relationship to be true with SW4350, and are impressed with its performance. But please understand, SW4350 is not exactly the same propellant as H4350. Ranked in fastest to slowest of the 4350 derivatives: H4350, IMR4350, Accurate 4350, SW4350. SW4350 has tremendous capabilities across virtually all long-range class and magnum class centerfire rifle ammunition. Despite SW4350 being an extruded propellant, it exhibits good flow characteristics through a volumetric powder dump. The grain is narrow, and cut short. The density of SW4350 is approximately 0.9 grams/cc. It contains a level of flash suppressant. Its extruded geometry is of a narrow diameter, and cut short. Therefore, its drop consistency through a volumetric charger is quite consistent for an extruded propellant. Under the Lovex brand, this propellant is referred to as S070. 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
