Sierra's Sports Master 125 grain Jacketed Hollow Point is a .357in diameter, flat-base handgun bullet built for handloaders reloading .38 Special and .357 Magnum. The Power Jacket design uses serrated skiving and a purpose-built cavity to promote rapid, even expansion on impact, giving strong energy transfer alongside good weight retention. A cannelure allows secure crimping in revolver and rifle cartridges chambered for these calibres. With a G1 ballistic coefficient of 0.133 and a sectional density of 0.14, it is accurate enough for target and silhouette shooting while offering genuine expansion for small game and vermin control 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.
