20 Gauge Magnum

20 GA 3" 5 28g/437grs, 1oz SL-203M

A heavy one-ounce Brenneke® slug, backed by three inches of magnum power, makes your three-inch twenty put many 12 gauges to shame. Velocity and energy both are excellent to 100 yards and beyond. The flat trajectory means no worries about holding high or low.

Bottom line, you cannot buy a slug that provides better performance in a 20 gauge shotgun. Or better performance on a deer.
