The Brenneke SL203M Magnum delivers exceptional stopping power and accuracy for hunters pursuing big game with 20-gauge shotguns. This premium slug ammunition combines the proven Brenneke design with magnum performance in a 3-inch shell loaded with a 1-ounce slug.

What Makes This Different

The SL203M features Brenneke's signature attached wad system that maintains slug stability throughout flight, delivering superior accuracy compared to standard foster slugs. The magnum loading generates higher velocities than standard 20-gauge slugs while maintaining manageable recoil. This design ensures consistent expansion and penetration on medium to large game animals.
