Forster Collet for Bullet Puller .400

• .400 Bullet Diameter Fit: Sized for .400 bullets, this collet gives the bullet puller a secure grip so loaded rounds can be disassembled with less slipping and less risk of marking the bullet.
• Solid Steel Construction: The steel body stands up to repeated reloading-bench use and keeps the gripping surfaces stable, which helps maintain consistent pulling force over time.
• Heat-Treated Build: Heat treatment improves wear resistance where the collet clamps and releases, supporting smoother operation during frequent cartridge disassembly.
• Hand-Polished Finish: The polished working surfaces promote smooth opening and closing, making the puller easier to operate and helping reduce drag during bullet removal.
• Fits Standard and Universal Bullet Pullers: One collet works with both Forster puller types, which simplifies setup for reloaders already using Forster case-preparation tools.

About the Bullet Puller Collets Series

Forster Bullet Puller Collets are purpose-built accessories for the company’s reloading and case-preparation system. Rather than using a one-size-fits-all gripping method, the series is arranged by specific bullet diameter, allowing the puller to clamp the bullet more precisely for controlled disassembly. This approach suits reloaders who want to correct seating depth, salvage components, or break down loaded ammunition with better consistency than improvised methods.

Across the series, the design stays straightforward and durable: solid steel, heat-treated, and hand polished for smooth operation. The collets are made to fit both the Standard and Universal Bullet Pullers, so the user can match the correct diameter to the bullet being pulled without changing to a different accessory system. In practical use, that means more secure bullet retention, less chance of slipping under load, and a cleaner workflow at the bench for precision handloading and ammunition correction.

About the Forster Collet for Bullet Puller .400

The Forster Collet for Bullet Puller .400 is the dedicated choice for reloaders working with .400 bullet diameter projectiles. In a bullet puller, correct collet sizing matters because the grip must be firm enough to hold the bullet during extraction without relying on excessive force. By matching the collet to the bullet diameter, this model helps the puller clamp more positively, which supports smoother disassembly and better control when correcting ammunition or recovering components.

Its steel construction and heat-treated build are practical advantages for bench use. The collet is repeatedly tightened, released, and exposed to friction, so material stability directly affects how consistently it performs over time. The hand-polished finish further improves handling by helping the collet move smoothly in operation rather than feeling rough or sticky under load.

This model is also useful for reloaders who already use Forster equipment because it fits both the Standard and Universal Bullet Pullers. That compatibility makes it a simple caliber-specific addition to an existing setup. For ammunition maintenance, load correction, or component recovery, the .400 collet gives the puller the properly sized contact point needed for controlled, repeatable bullet removal.

About Forster

Forster Products dates its history to 1935 and focuses on precision reloading and gunsmithing tools. Based in Lanark, Illinois, the company states that its products are made in the United States. Forster is especially well known among handloaders for tools built around repeatable alignment and careful dimensional control rather than unnecessary complexity.

Its product range includes reloading dies, case trimmers, headspace gauges, and sight-mounting fixtures, showing a long-standing emphasis on bench precision. Among its better-known designs is the Co-Ax Press, while its Bench Rest Seater Dies use a close-fitting chamber to help align the case and bullet during seating. That background is directly relevant to accessories such as bullet puller collets, where consistent fit, smooth operation, and durable machining matter in everyday reloading work.
