Self Defense Ammo

I recently (and accidentally) stumbled on a great resource for those even remotely interested in ballistics. In this article, the team at Lucky Gunner tests ammo of all brands, weights, and calibers to determine the "best" self defense round available on the market today. The best part? They don't make a definitive statement that Ammo X is better than Ammo Y... they provide the ballistics data, and you decide what you're most confident in.

Each test consisted of a 5 shot group, and the data recorded included:

  1. Average penetration depth
  2. Average expansion diameter
  3. Average muzzle velocity
