Lee Precision 92218 Micrometer Adjust Screw Large Rifle 35 Cal Or Larger

The Lee Precision 92218 Micrometer Adjust Screw is a precision upgrade for large rifle and magnum cartridge reloaders who demand repeatable bullet seating depth. If you're working with cartridges .35 caliber or larger—including straight-wall magnums and specialty rounds—this micrometer adjustment system replaces the standard screw on any compatible Lee bullet seating die, giving you the fine control that matters when chasing accuracy and consistency across multiple loadings.

Unlike the stock seating die adjuster, this micrometer screw eliminates the frustration of hunting between clicks. The integrated friction ring delivers smooth, infinitely adjustable movement so you can dial in your exact seating depth without the binding or mechanical detents that make splitting thousandths nearly impossible. Laser-engraved divisions mark every .001" of travel—the same scale you'd read on a precision depth micrometer—so you can record your setting and return to it shot-for-shot, load after load, without guesswork or trial-and-error.

Lee designed this adjuster to transfer between dies, though at its modest cost, many reloaders keep one mounted on each seating die for their large-rifle calibers. Whether you're loading for elk, precision rifle competition, or handloaded magnum hunting ammo, this small upgrade pays dividends in consistency and ease of setup.

Specifications

Frequently Asked Questions

Which Lee seating dies does this micrometer screw fit?

The 92218 is designed for large rifle cartridges .35 caliber and larger that use the standard Lee bullet seating plug. Check your die's specs or contact Lee to confirm compatibility with your specific cartridge and die model.

Can I move this micrometer adjuster between different seating dies?

Yes. The micrometer screw is designed to transfer between compatible Lee bullet seating dies, though it is economical enough that many reloaders prefer to install one on each die for convenience.

How do I record and repeat my seating depth setting?

The laser-engraved divisions mark every .001" of adjustment, just like a precision depth micrometer. Simply note which division aligns with your reference point when you dial in your desired seating depth, then return to that same setting whenever you reload the same cartridge.

What's the advantage over a standard seating die screw?

The integrated friction ring provides smooth, click-free adjustment so you can fine-tune seating depth in fractional thousandths without the binding or mechanical detents of a standard adjuster. This repeatability is crucial for accuracy-focused reloaders.
