At a mail-order store in the Dallas area, they list Federal Hydra-Shock bullets as being for law enforcement sale only. You can't buy it from them unless you have a peace officer's license. I bought some years ago, and still have some, so I was surprised to learn this. Is this true everywhere, or just at that one store or maybe just in Texas? And if so, why? Is it that potent, or what? I keep a pistol in the house solely for home defense, and obviously don't burn up many shells, so it has been awhile since I have even looked for pistol bullets.
