Remington Ultimate Defense 12 Gauge #4 Buckshot, 5-Round Box

Remington’s Ultimate Defense line (part no. 20637) loads this 12 gauge shell with #4 buckshot in a standard 2.75-inch hull, built for shooters who want a dense pattern and confident stopping power from a home-defense shotgun. Remington engineers the Ultimate Defense series for tight, effective short-range patterns through a smoothbore barrel, favoring one-shot confidence over long-range reach. The #4 pellet size carries a higher pellet count than larger buckshot sizes like 00 buck, trading individual pellet size for more hits on target at typical home-defense distances. In shotgun shells built specifically for defense, this is a purpose-engineered load.
