L.E. Wilson 300 Aac Blackout Micrometer Top Bullet Seater
$135.52
The L.E. Wilson 300 AAC Blackout micrometer top bullet seater is a precision reloading die built for shooters who demand repeatable, exact bullet seating depths. Constructed from durable stainless steel, this arbor-press die features a micrometer adjustment system that lets you dial in bullet seating with 0.001" resolution—critical for handloads that perform consistently downrange, whether you're working up loads for subsonic hunting rounds or suppressed precision shooting.
What sets this seater apart is its practical design: the threaded cap makes major adjustments straightforward, and the 0.001" scale gives you the fine control that separates good ammunition from genuinely accurate ammunition. Because it's an arbor seater, you can seat bullets long, then take the die and press to the range to verify actual cartridge performance before committing to a full loading session. That saves time and ammunition during the critical testing phase.
If you're reloading 300 AAC Blackout for a suppressed rifle, precision AR pistol, or dedicated subsonic hunting rifle, this die rewards attention to detail. It's the kind of tool that makes the difference when you're chasing consistent velocity nodes or fine-tuning ammunition for a specific barrel.

Frequently Asked Questions
What press do I need to use this seater die?
This die is designed to work with an arbor press. It is not compatible with standard reloading presses like progressive or single-stage turret presses.
How precise is the seating depth adjustment?
The micrometer adjustment system reads in 0.001" increments, allowing you to dial in bullet seating depth with that level of precision.
Can I use this die to test seating depth at the range?
Yes. One of the practical advantages of this arbor seater is that you can seat bullets long, then transport the die and press to the range to test how the ammunition performs before committing to a full loading batch. This saves multiple trips to the range during load development.
Is this die suitable for subsonic 300 AAC Blackout loads?
Yes, this die is built for 300 AAC Blackout and works well for both subsonic and supersonic loads. The precise micrometer adjustment helps ensure consistency regardless of your intended application.
