Winchester 760 Smokeless Gun Powder: Versatile Magnum-Capacity Rifle Propellant

Winchester 760 is a spherical (ball) rifle powder with a moderate-to-slow burn rate, developed to duplicate .30-06 Springfield factory-load ballistics and to perform reliably across a wide range of medium and large-capacity rifle cartridges. It’s a longtime favorite among rifle reloaders for its versatility, clean metering, and consistent performance in everything from standard big-game cartridges to full-power magnums.

Versatile, Consistent Rifle Performance

Winchester 760’s spherical granules flow smoothly through powder measures and progressive presses, supporting consistent charge weights load after load. Its ideal flow characteristics give it an edge over other propellants with similar burn rates, and its moderate-to-slow burn rate makes it well suited to medium and large rifle cases that need a full case of powder to reach optimal velocities.

Application Versatility

Winchester 760 is a genuine rifle powder — not a pistol or shotshell propellant — and performs well in .22-250 Remington, .300 Winchester Magnum, .300 WSM, and other medium-to-large capacity rifle cartridges where a moderate-slow burn rate is called for. If you’re comparing options in the medium-burn-rate rifle powder class, Winchester 748 is a faster-burning alternative suited to smaller-capacity cartridges like .223 Remington, while Winchester StaBall Match offers a match-grade option for precision rifle shooters.

Load Development

Always use published, manufacturer-tested load data when developing rifle loads with Winchester 760. Start at the published minimum charge and work up in small increments, weigh every charge on a calibrated scale, and chronograph each string to find the most consistent load. Keep your primer brand, bullet lot, and brass lot constant during development, watch for pressure signs, and document charge weight, seating depth, primer, and chronograph results so successful loads can be reproduced.
