Alliant is now shipping an advanced medium-fast burn rate pistol powder that has many important qualities. New Sport Pistol powder exhibits excellent temp stability. That means you can develop a stout load and not worry about hot days at the range. Sport Pistol was also formulated to work with the new generation of polymer-coated bullets. Alliant’s engineers tell us: “This new propellant is very advanced. The chemistry of Sport Pistol is not similar to Bullseye or other older pistol powders. Sport Pistol delivers precise performance with all bullet types, but the low muzzle-flash formulation was optimized for polymer-coated bullets. Other double-base powders can dissolve the polymer coatings at the bullet base, and this exposes the lead to vaporization due to the intense heat during the ballistic cycle.” Alliant says this powder burns clean and gives “extremely reliable cycling, excellent charging/case fill [with] ballistics that lend themselves to a range of popular loads.”

How Sport Pistol Compares to Other Pistol Powders
It looks like Alliant’s new Sport Pistol can be used to replace W231 and HP-38, two popular powders for 9mm, .40 S&W, and .45 ACP cartridges. One pistolero notes: “Just looking at the load data for Sport Pistol, charge weights are similar to W231/HP-38 and Alliant advertises it as ‘medium fast’ burning for precision and action shooting competition. I say Alliant released a competing powder for W231/HP-38 that is less temperature sensitive.”
