The 240 grain #8820 Jacketed Hollow Cavity SportsMaster bullet was introduced in 1977 in response to requests for a "standard" weight bullet for the 45 Colt cartridge. The skived PowerJacket was added in 1984, making this bullet an excellent choice for 45 Colt vintage or modern handguns. Vintage models usually had a .454 inch diameter bore. However, modern Colt, Ruger, Smith & Wesson, Taurus, and most other handguns, including replicas of the Colt Single Action Army, will have barrels with a .451 inch bore. This bullet can be used in vintage 45 Colt handguns, but sizing cases may require special attention in older reloading dies. The 240 grain #8820 bullet has a cannelure for roll crimping, and it may be loaded into 45 Colt cartridges to be used in rifles with tubular magazines. This bullet is very effective for hunting because of the reliable expansion of the hollow cavity PowerJacket design and trademark Sierra accuracy. The reliable expansion characteristics of this bullet make it suitable for cartridges ranging from the 45 ACP up through moderate loads in the 454 Casull for either hunting or target competition.
