Redding 300 Remington Ultra Magnum Bushing Die Set$283.94
Availability: In Stock
The Redding 300 Remington Ultra Magnum bullet seating die gives precision reloaders the control they need to dial in consistent cartridge assembly. Built for shooters who demand tight tolerances, this 7/8-14 threaded die pairs a micrometer-adjustable mechanism with a smooth, low-friction sliding chamber. Whether you're working up loads for long-range hunting or competitive shooting, seating depth directly affects accuracy, velocity consistency, and pressure—and this die lets you fine-tune it to the thousandth of an inch.
The micrometer adjustment calibrates in .001" increments with infinite adjustment and no clicks, giving you the repeatability you need when you're chasing nodes or testing bullet jump. The zero set feature means once you've dialed in your preferred seating depth, you can return to that setting reliably load after load. The machining is precise and the chamber action is exceptionally smooth, which matters when you're handling hundreds of rounds and repeatability is everything.
This is a standalone die, sold separately, and works within the Redding reloading die family for 300 Remington Ultra Magnum. If you reload this magnum cartridge and take seating depth seriously—and if you own a 300 RUM, you likely do—this die earns its place on the press.

The Redding 300 RUM seating die has a 7/8-14 thread, the standard for full-length rifle reloading presses. It will work with any single-stage or progressive press that accepts standard rifle dies in that thread size.
This seating die is sold separately. Redding also offers it as part of complete die sets for the 300 Remington Ultra Magnum; check our store for set options if you need a full die package.
The micrometer allows adjustment in .001" increments and is infinitely adjustable with no click stops, meaning you can dial in any seating depth you need and return to it reliably. The zero set feature locks in your preferred depth as a repeatable reference point.
We include the seating die itself. The die fits standard 7/8-14 threaded presses; you'll use your press's shell holder and reloading components as normal.
