Hornady 397139 A-Tip Match Bullet Seating Stems - 6mm Precision Reloading Component
Hornady
The Hornady Click-Adjust Bullet Seating Micrometer is a precision reloading upgrade that replaces the standard seating stem on Hornady rifle seating dies. If you're already running a Hornady die set and want to dial in bullet seating depth with repeatable accuracy, this micrometer gives you the control of a dedicated seating die without buying an entirely new setup. It's built for reloaders who care about consistency—whether you're chasing benchrest groups or just tired of guessing when your bullet sits deep enough.
The core advantage is tactile, indexed adjustment: every click represents .001" of movement, so you feel and hear when you've made a change. That feedback matters when you're trying to dial in the same seating depth across a hundred rounds. Once you've found the sweet spot for your load, the micrometer holds the setting, so repeatability becomes straightforward. No more squinting at witness marks or second-guessing whether you turned the adjustment stem a quarter turn or half.
Installation is simple—it's a drop-in replacement for the seating adjustment stem already on your Hornady rifle dies. No new die required, no complicated setup. If you've already invested in Hornady equipment and you want to tighten your reloading tolerances without a full die purchase, this is a practical step up.

Yes—this micrometer replaces the standard seating adjustment stem on Hornady rifle seating dies. If you already own a Hornady seating die, you can swap out the old stem and install this upgrade.
Each click you make adjusts bullet seating depth by one-thousandth of an inch. This precise, indexed movement lets you fine-tune seating depth in small, repeatable increments and lock in consistent bullet depth across your entire batch.
No. This is a replacement component for the seating adjustment mechanism on dies you already own. It upgrades your existing Hornady rifle seating die without requiring a separate die purchase.
