Forster Products Ster Bushing Full Length Sizing Die Bench Rest Ultra Micrometer Seater UFB4331

The Forster Products Bushing Full Length Sizing Die with Bench Rest Ultra Micrometer Seater gives precision reloaders a genuinely different approach to brass preparation. Unlike standard sizing dies that treat all necks the same way, this system lets you control exactly how much squeeze you apply to the neck while the body and shoulder get sized for a consistent chamber fit. That level of control over neck tension is what separates ammo that shoots 0.3 MOA from ammo that shoots 0.8 MOA—especially once you're chasing small groups at distance or preparing rounds for competition.

The die sizes the body and bumps the shoulder back just enough to fit a minimum-sized SAAMI chamber, which means less metal movement overall and less work-hardening of the brass. That translates to longer case life and more reloading cycles per piece of brass. The included bushings let you dial in the exact neck tension your specific brass and bullet combo needs; you're not forced into a one-size-fits-all solution. The Bench Rest Ultra Micrometer Seater mechanism gives you repeatable, fine-grained bullet seating depth adjustments—critical when you're building ammo to exacting standards.

This is the tool you reach for when basic accuracy isn't enough. If you're loading for a bolt-action rifle where precision matters and you have the time to dial in your process, the control and repeatability justify the investment. Serious bench rest shooters, long-range hunters, and competition loaders rely on Forster's engineering for exactly this reason.

Frequently Asked Questions

What's the advantage of a bushing sizing die over a standard full length sizer?

A bushing system lets you adjust neck tension independently of body and shoulder sizing. You can size the case body and shoulder to fit your chamber while controlling exactly how much the neck is worked—something a standard die does all at once. That control is what lets serious reloaders optimize accuracy and extend case life.

Why does neck tension matter for accuracy?

The tension between the case neck and your bullet directly affects how consistently the bullet is released from the case—and bullet runout and release consistency drive accuracy. Different brass and bullet combos need different neck tension; the included bushings let you find your load's sweet spot.

How many times can I reload brass with this die?

Because the bushing system minimizes unnecessary working of the brass—sizing only as much as needed to fit your chamber—you'll get more reloading cycles per case compared to standard full length sizing. The exact number depends on your brass quality and how many times you resize, but the reduced work-hardening directly extends case life.

Is the micrometer seater included, or do I need to buy it separately?

The Bench Rest Ultra Micrometer Seater Die is included in this set along with the sizing die and 3 bushings. You have both the sizing and seating components ready to go.
