45 CAL (.4515) 300GR JSP

Despite its "soft point" title the Sierra 300 grain #8830 Jacketed Soft Point (JSP) SportsMaster is the single hardest bullet Sierra has produced. Utilizing a 6% antimony 4% tin 90% lead alloy core this 300 grain JSP will expand only on the toughest game when driven at absolutely top-end velocities of up to 1550 fps. Intended primarily for the strongest 45 Colt revolvers (Freedom Arms Dan Wesson and Ruger revolvers) the single-shot T/C Contenders and the 454 Casull revolvers this bullet is an excellent selection for the heaviest game on any handgunner's agenda. Because of its length and solid construction this bullet cannot be used in Colt Single Action Army revolvers or their modern reproductions. This bullet was introduced by Sierra in 1994.
