Forster Products Ster Bushing Full Length Sizing Die Bench RestôøΉ Ultra Micrometer Seater D

The Forster Products Bushing Full Length Sizing Die with Ultra Micrometer Seater represents a serious upgrade for reloaders who demand precision and consistency. This die set combines a bushing-based full length sizing die with a micrometer-controlled seating die, giving you the fine control necessary for match-grade ammunition and long-range hunting loads. If you're loading for accuracy-critical applications—whether benchrest, precision rifle, or long-range hunting—this system lets you dial in neck tension and bullet seating depth independently, eliminating the guesswork that plagues standard dies.

The bushing design is the key advantage here. Rather than a fixed neck opening, you choose the bushing size to control exactly how much tension your resized brass exerts on the bullet. This approach means your necks work less during the sizing stroke, which translates to longer case life and more consistent loads. At the same time, the body and shoulder are sized down to fit a minimum SAAMI chamber, ensuring reliable feeding and chamber fit across various firearms. The micrometer seater gives you repeatable bullet seating depth to within tenths of a thousandth—the kind of control benchrest and precision shooters expect.

This set includes three bushings, giving you flexibility to fine-tune neck tension for different brass conditions or bullet styles without buying additional dies. Setup is straightforward if you're familiar with reloading dies, though the precision nature of the equipment rewards careful initial adjustment.

Frequently Asked Questions

What caliber is this die set for?

The product record does not specify a caliber. Contact us or check the product packaging to confirm the intended caliber before ordering.

What's included in the set?

The set includes a bushing full length sizing die, an ultra micrometer seater die, and three bushings to allow you to adjust neck tension for different brass conditions or bullet styles.

How does the bushing system improve accuracy?

The bushing lets you control neck tension precisely—how tightly the resized neck grips the bullet. This reduces inconsistent neck working during sizing, which improves load-to-load consistency and extends case life. The micrometer seater allows you to set bullet seating depth repeatably to very tight tolerances, both of which contribute to tighter velocity spreads and better accuracy.

What's the difference between this and a standard full length die?

Standard dies have a fixed neck opening and rely on bushing-less sizing. This set's bushing design lets you select the exact amount of neck tension you want, rather than accepting whatever tension the die provides. The micrometer seater also offers far finer control over seating depth than a standard press and seating stem.
