Sierra's Sports Master 158 grain Jacketed Soft Point is a .357in diameter handgun bullet built for handloaders reloading .38 Special and .357 Magnum. The Power Jacket design uses serrated skiving to promote consistent, controlled expansion across a wide range of velocities, giving reliable weight retention and deep penetration once it reaches the target. A cannelure allows secure crimping in revolver and rifle cartridges chambered for these calibres. With a G1 ballistic coefficient of 0.175 and a sectional density of 0.177, this is the heaviest of Sierra's common .357 Sports Master weights, favoured by handloaders working up hunting loads for medium-sized game in .357 Magnum where deep penetration matters, as well as heavy target and silhouette loads. This is a bullet head for handloading, not loaded ammunition — supplied without primer, powder or case for use by competent reloaders working to safe, published load data for their calibre. Each box holds 100 non-coated bullets ready for the reloading bench.
