In a situation where you have to clear your carry gun frequently and do not wish to go through boxes of premium ammo rotating you chambered rounds into the training box:
Hornady Critical Duty is crimped to prevent bullet setback in autos,is it an OK idea to have the first round be CD with the rest in the mag your preferred defense load? Is this not a good idea? Does the crimp actually work for it's intended purpose? Why don't other premium manufacturers crimp their loads?
