Choosing home defense ammunition is a delicate task since it can be difficult to find a round with the performance to stop an aggressor, yet not over-penetrate.For example, hollowpoint handgun ammunition is normally considered a standard round for personal defense. The problem is that when a hollowpoint bullet penetrates through a barrier, or even a few layers of cloth, before hitting the intended target, it tends to perform more like a full metal jacketed round. Particles and debris fill up the hollow cavity of the bullet and prevent it from expanding as it was designed to do.
Federal Premium Ammunition has a product that solves this problem. Its Guard Dog Home Defense ammunition was designed from the ground up specifically for home defense. It features a unique expanding full metal jacket design which effectively eliminates threats while not over-penetrating drywall and plywood barriers.
Federal’s Guard Dog ammo works by using an expanding polymer core. The full-metal jacket design cannot fill with debris from a wall or heavy fabrics yet, upon impact, the bullet expands to as much as twice the original diameter.
Tests conducted by Federal showed its new design could pass through four layers of drywall and then stop in less than 15″ of ballistic gelatin. Traditional hollowpoint ammunition, on the other hand, passed through four layers of drywall and continued to completely penetrate 15″ of ballistic gel before exiting the other side.
