In the realm of firearms and ammunition, precision and reliability are paramount. Enter the 240 grain #8820 Jacketed Hollow Cavity SportsMaster bullet—a design born from necessity in 1977 for enthusiasts of the .45 Colt cartridge seeking a standard weight projectile. This bullet stands as a testament to engineering prowess, featuring Sierra's PowerJacket technology introduced in 1984, which has since become synonymous with excellence.
The .45 caliber (specifically .4515 inch) projectile is tailored for both vintage Colts with larger bore diameters (.454 inch) and modern handguns like those crafted by Colt, Ruger, Smith & Wesson, Taurus, among others including replicas of the iconic Colt Single Action Army that utilize a .451 inch bore. This versatility ensures it remains indispensable across generations of firearm designs.
One must not overlook its structural integrity—exemplified by its cannelure designed specifically for roll crimping—allowing seamless integration into cartridges destined for rifles equipped with tubular magazines. Furthermore, this bullet’s application extends beyond mere compatibility; it thrives in diverse scenarios ranging from hunting expeditions to target competitions.
The ballistic performance is noteworthy: With sectional density at .168 and varying ballistic coefficients—ranging from .150 at velocities above 1100 fps to .170 below 900 fps—the #8820 ensures optimal trajectory stability and energy retention upon impact. Its hollow cavity facilitates dependable expansion on contact making it an ideal choice whether you are deploying rounds through a venerable revolver or pushing moderate loads up to 1400 fps in high-pressure platforms like the mighty 454 Casull.
Ultimately, what distinguishes this Sierra creation is not merely its adaptability but also its unwavering commitment to accuracy—a hallmark trait appreciated by marksmen who demand nothing less than perfection shot after shot.
