L.E. Wilson S/S Bullet Seater Die W/ Micrometer Adjustment 308 Win.
The L.E. Wilson S/S Bullet Seater Die with Micrometer Adjustment for .308 Winchester is built for reloaders who demand consistency and precision in every round. This stainless steel die lets you dial in your bullet seating depth with repeatable accuracy, using a micrometer top scaled in 0.001" increments so you can nail the exact depth you want, shot after shot. Unlike fixed seating dies, the micrometer design and threaded cap adjustments make it easy to experiment and dial in your load without guessing or pulling bullets repeatedly.
One practical advantage of this arbor seater design: you can seat bullets long at the reloading bench, then bring the die and an arbor press to the range to test actual seating depth in your rifle's magazine or chamber. That flexibility means fewer trips back and forth and more time testing loads. It's the kind of tool that pays for itself in saved ammunition and range time once you're serious about load development.
L.E. Wilson dies are known for quality construction and straightforward operation. This seater is purpose-built for .308 Winchester, so you get the right fit for your cartridge without compromise. Keep in mind you'll need an arbor press to use this die—it's not a press-mounted die, but that portability is part of what makes it valuable for fine-tuning your loads.

Frequently Asked Questions
What press do I need to use this die?
This is an arbor seater die designed to work with an arbor press, not a reloading press mounted on your bench. You'll need a separate arbor press to operate it.
Can I use this seater for other calibers?
No, this die is specifically chambered for .308 Winchester. L.E. Wilson makes micrometer seater dies for other calibers, but this one is sized for .308 Win only.
How do I adjust the seating depth?
The micrometer top scales in 0.001" increments, allowing you to dial in your exact seating depth. Major adjustments are made with the threaded cap. This precision lets you test and refine your seating depth without trial and error.
Why would I want to test seating depth at the range?
With an arbor seater, you can seat bullets slightly long at home, then bring the die and arbor press to the range to test how your loaded rounds perform in your actual rifle before committing to a full batch. This saves ammunition, time, and multiple trips to the range during load development.
