Redding Reloading Equipment
The Redding 280 Ackley Improved bullet seating die is a precision reloading tool built for handloaders who demand consistency in their ammunition. Whether you're assembling match ammo for the range or hunting loads that need to perform in the field, a quality bullet seating die is central to producing reliable, accurate rounds—and this Redding die brings competition-grade machining to that critical step. The 7/8-14 threaded design fits standard reloading presses, making it a straightforward addition to most reloading setups.
What sets this seating die apart is its micrometer adjustment system. The micrometer is calibrated in .001" increments and operates smoothly across its full range with no detents or click-stops—you dial in your exact seating depth, period. That infinitely adjustable approach means you can fine-tune bullet seating to tenths of a thousandth, which matters when you're chasing tight velocity spreads or testing load development. The sliding chamber mechanism is engineered for a smooth, consistent feel every time you cycle the press handle, reducing variability in the seating process itself.
The die also includes a zero-set feature, letting you calibrate the micrometer to your preferred seating depth so you can return to that setting reliably across reloading sessions or when switching between different loads. That's a practical advantage if you're running multiple loads for the same rifle or comparing seating depths during load work-up. Redding's reputation for precision machining shows in the fit and finish—this isn't a loose, sloppy tool.
| Cartridge | .280 Ackley Improved |
| Die Type | Bullet Seating Die |
| Thread Size | 7/8-14 |
| Micrometer Increments | .001 inch |
| Adjustment Style | Infinitely adjustable (no detents) |
| Brand | Redding |
The Redding 280 Ackley Improved seating die has a 7/8-14 thread, which is the standard size for most single-stage and turret reloading presses. Check that your press accepts standard 7/8-14 dies before ordering.
This die's micrometer has no detents or clicks—you turn the knob smoothly to any position within its range and the setting holds. That gives you finer control over seating depth without being locked to specific increments. The .001" calibration means you can dial in any depth you need within the die's range.
The zero-set feature lets you calibrate the micrometer to read zero (or any reference number) at your preferred seating depth. Once you dial in a load you're happy with, you can note the zero position and return to it quickly in future reloading sessions, making setup faster and more repeatable.
Yes. The precision of this seating die works for any 280 Ackley Improved ammunition you're building, whether it's for load development, match shooting, hunting, or practice. The micrometer control simply lets you dial in your exact seating depth regardless of the application.
