Winchester Super Match Competition Grade 12ga 2.75", 1oz Rifled Slug, 10rd Box

Winchester Super Match 12 Gauge 2-3/4-Inch 1 oz Rifled Slugs, 10-Round Box

Winchester Super Match 12 Gauge rifled lead slug ammunition is a specialized competition shotshell built around a 2-3/4-inch high-brass configuration and a nominal velocity of 1,300 fps. The exact SM12RS load is engineered for competition slug stages and range use, with a robust hull intended to maintain shape and support reliable feeding in compatible box-magazine-fed competition shotguns.

The high-brass head and thick-walled tube form a professional-grade package for demanding stage work. Reliable cycling still depends on the shotgun, magazine, recoil system, gas setting, maintenance condition, and shooter technique, so competitors should function-test the exact load before relying on it in a match.

Box-Mag-Ready Hull and High-Brass Head

The thick-walled hull and high-brass head are designed to resist deformation while shells are stacked under spring pressure in a detachable box magazine. That construction supports consistent presentation and extraction in compatible competition shotguns, but it does not replace firearm-specific testing or magazine maintenance.

One-Ounce Rifled Lead Slug

The one-ounce rifled lead slug is engineered with an alloy that obturates to the bore and supports consistent accuracy. A rifled-slug configuration is designed for suitable smoothbore applications, but barrel type, choke, sights, and firearm guidance must be confirmed before use. Zero and test the exact shotgun rather than assuming a common point of impact.

Competition Velocity and Function Testing

The published nominal velocity is 1,300 fps. Actual velocity, recoil impulse, cycling behavior, and point of impact can change with barrel length, chamber, choke, temperature, and firearm setup. Test the exact ammunition in the exact shotgun and magazine configuration before competition.
