Hornady Standard Lock-N-Load Pistol Metering Insert

The Hornady Standard Lock-N-Load Pistol Metering Insert is a precision component designed for shooters who reload pistol ammunition and demand consistency in their charge weights. This insert fits into the Hornady L-N-L Powder Measure system and provides a smaller metering chamber optimized for the lighter powder charges typical of handgun cartridges. If you're building match-grade 9mm, .45 ACP, or other pistol loads, this insert gives you the accuracy control needed to dial in repeatable velocities and tight shot groups at the range.

Reloading pistol ammunition requires a different approach than rifle work—powder charges are smaller, tolerances are tighter, and consistency matters as much as with centerfire rifle loads. The pistol insert is engineered to handle charge weights between 0.5 and 17 grains, covering the full spectrum of common handgun powders. Because it's part of the modular L-N-L system, swapping between rifle and pistol metering is fast and straightforward, letting you shift between projects without downtime or frustration.

This is the standard metering insert for pistol work. If you want the ability to make fine incremental adjustments and dial back to previous settings, Hornady also offers the Micrometer Pistol Insert, which pairs with this same rotor system for even greater precision control. Either way, you'll need the Pistol Rotor and the Standard Metering Insert itself to operate the measure.

Frequently Asked Questions

Do I need anything else to use this pistol metering insert?

Yes. You'll need both the Pistol Rotor and the Standard Metering Insert to use this component in your L-N-L Powder Measure. The insert alone is a replaceable metering chamber; it works as part of the larger rotor assembly.

What charge weights does this insert handle?

The Standard Pistol Metering Insert meters powder charges between 0.5 and 17 grains, covering standard pistol loads across common handgun calibers.

Can I upgrade to micrometer adjustment later?

Yes. Hornady offers a Micrometer Pistol Insert that allows you to make fine incremental changes and return to previous settings. You can swap it into the same rotor system.

Is this insert only for pistol reloading?

This insert is designed and optimized for pistol ammunition. For rifle reloading, you'll use a different rotor and metering insert designed for the larger charge weights typical of centerfire rifle cartridges.
