Walk into any gun shop and you’ll see a wall of hollow points, each box claiming to be the best stopper on the market. Most of that is marketing. Here’s what’s worth paying attention to.
Penetration comes first. The FBI’s testing protocol has long used 12 to 18 inches of penetration in calibrated ballistic gelatin as the benchmark. Too little, and the round may not reach vital structures, especially through heavy clothing or at an angle. Too much, and you risk over-penetration. Most major-brand defensive loads are designed around this standard.
Expansion is second. A hollow point that expands reliably creates a larger wound channel and tends to stay in the target. But a round that expands beautifully in bare gel and plugs up with denim and stops expanding isn’t doing its job. Look for testing through barrier materials, not just bare gel.
Reliability in your gun is non-negotiable. The best load on paper means nothing if it doesn’t feed in your pistol. Run at least a couple hundred rounds of your chosen carry ammo through your gun before you trust it. Yes, it’s expensive. It’s also the only way to know.
Rotate your carry ammo. Rounds that get chambered over and over can suffer bullet setback, where the bullet gets pushed deeper into the case and raises pressure. Inspect your top round and rotate it out regularly. Many people shoot their carry ammo at the range once or twice a year and replace it with a fresh box.
Practice ammo matters too. Try to train with FMJ that has similar weight and velocity to your carry load so recoil and point of impact feel the same.
What are you carrying for defensive ammo, and how did you pick it? Has anyone had a load that didn’t run reliably in their gun?
