The Forster Products Inc Ultra Micrometer Seater Die for 300 WSM brings precision bullet seating to your handloading bench. Built for reloaders who demand consistency and repeatability, this rifle die combines Forster's reputation for quality steel and tight tolerances with a micrometer-adjusted seating mechanism that lets you fine-tune bullet depth to exacting standards. If you're loading for a 300 WSM and want to eliminate guesswork from the seating stage, this die puts the control in your hands.
What sets the Ultra Micrometer Seater apart is its ability to adjust seating depth in increments as small as .0005 inch to .001 inch. That level of precision matters when you're chasing tight groups or trying to seat bullets consistently relative to your rifling. Once you dial in a setting that works, you can record it and return to that exact depth whenever you load the same bullet—no fumbling with trial and error on your next batch.
Like all Forster reloading dies, this seater is hand-finished before and after heat treatment to ensure a fine surface that resists wear and promotes smooth operation. The signature Forster Cross Bolt Die Locking Ring tightens both ends of the split ring evenly, rather than relying on a single screw threaded into the die itself. That design reduces the risk of distortion and helps maintain the die's precision over thousands of rounds.
| Product Name | Forster Ultra Micrometer Seater Die for 300 WSM |
| Manufacturer | Forster Products Inc |
| Model Number | U00101 |
| Cartridge | 300 WSM |
| Type | Rifle Seater Die |
| Adjustment Increment | .0005 to .001 inch |
The Ultra Micrometer Seater features a precision micrometer adjustment that lets you change bullet seating depth in very small increments (.0005 to .001 inch), then record and return to that setting. This eliminates the need to reset by hand every time you load a new batch, and allows you to dial in your exact preferred depth for maximum accuracy and consistency.
Yes—this die is specifically chambered for 300 WSM. It is not compatible with other cartridges.
Instead of tightening a single screw into the die's threads, Forster's Cross Bolt design tightens both ends of the split ring evenly. This approach reduces the risk of die distortion and helps maintain precision and concentricity over extended use.
Yes. Forster hand-polishes each die both before and after the heat-treating process to guarantee a fine finish and smooth operation.
