Sierra Sports Master 9mm bullets, 125 grains jacketed hollow point (Sierra part no. 8125), give handgun reloaders a jacketed bullet built to Sierra’s tight manufacturing standards for consistent expansion and accuracy. Sierra publishes ballistic coefficients across three velocity bands for this bullet: .124 at 1,200 feet per second and above, .137 between 900 and 1,199 feet per second, and .168 below 900 feet per second, letting handloaders dial in trajectory data with real precision rather than a single average figure. At .355-inch diameter and 125 grains, this is one of the most commonly reloaded 9mm bullet weights, suited to practice, competition, and duty-style handgun loads alike.
