Defender Shotshell Ammunition—

Defender Shotshell is available in 12 gauge, 20 gauge and .410 bore with multiple payload offerings including segmenting slugs, buck shot and combination loads.

Defender Close Range was designed with home defense in mind, where likely shooting distances are within 10-20 feet.  This load offers an incredibly high pellet count with approximately 100 copper plated lead #2 pellets which deliver tremendous energy on target while still reducing the risk of over penetration.  The load is further improved by a cushioned wad that reduces felt recoil and an engineered wad for consistent dense patterns at close range.

The .410 Defender ammunition is compatible in both handguns and shotguns and features a distinctive black hull and black oxide high-base head and combines plated Defense Disc™ projectiles and plated BB shot pellets. The result is the ideal personal defense load for short range engagement with the performance needed to reduce aim error and stop threats.
