I ranked the top 6 home defense calibers in America — .45 ACP, .300 Blackout, .357 Magnum, 12 Gauge, 5.56 NATO, and 9mm — and eliminated them one by one based on a single test: where does each one break down when your life actually depends on it?
Inside: overpenetration risks, capacity limitations, recoil problems, indoor muzzle blast, maneuverability in tight spaces, and what the FBI’s ballistics data actually says about stopping power.
Whether you’re protecting a house, an apartment, or a family with multiple shooters — this breakdown will change how you think about your setup.
