Hornady L-N-L Ammo Concentricity Tool

Hornady Lock‑N‑Load Concentricity Tool

Whether you make your own ammo or use factory ammo, there is always a chance that a bullet is not perfectly straight allined in the case. If this is the case, the bullet will take longer to stabilize during flight and there is a chance that you will have more spread in the shot pattern than you would like.

With the Concentricity Tool from Hornady you can get the bullet perfectly alligned in the center of the case again, you simply place the cartridge in the tool and turn the micrometer against the bullet, you can then see which way the bullet is standing, then you can bring the bullet back to the center with an adjustment knob so that your bullet is perfectly in the center.

The Concentricity Tool is suitable for calibers from .22/5.56 to .45 and can be screwed onto a workbench, for example. The tool can be used for homemade cartridges and factory ammo.
