Atlanta Arms Sci Features The Atlanta Arms Sci bullet measures .357 inch in diameter and weighs 125 grains a classic revolver bullet weight suited to both .38 Special and .357 Magnum handloading. Its jacketed hollow point design features a jacketed lead core built to expand reliably on impact giving handloaders a bullet capable of delivering real terminal performance for defensive and duty style loads. Because this bullet fits both .38 Special and .357 Magnum cases reloaders working with either cartridge can standardize on a single projectile for load development. The 125 grain weight has long been a favored choice among revolver shooters for its balance of velocity and controlled expansion. Sold 100 to a box this bullet provides the revolver handloader with a substantial supply for load testing and ongoing ammunition production. Atlanta Arms built its climate controlled manufacturing facility specifically to improve dimensional consistency across its projectile lines a difference that shows up as more uniform crimp and overall cartridge length on the reloading bench. That consistency is especially valuable for revolver shooters where uneven bullet dimensions can affect cylinder gap performance and accuracy. This Sci 125 grain JHP bullet is a component only meant strictly for handloading and not a ready to fire loaded cartridge.
