Redding Series C Seating Die For Straight Wall Cases .450 Bushmaster DEMO/USED

The Redding Series C Seating Die for straight wall cases in .450 Bushmaster is engineered for reloaders who demand precision and consistency. Built around Redding's proven Series C platform, this die uses a separate bottom punch that seats the case body directly to the shoulder—a technique favored for military and target ammunition where long-term accuracy matters. Whether you're assembling match rounds or developing a hunting load, the .450 Bushmaster seating die delivers the concentricity and control that serious reloaders expect.

The rear-punch design is the key to this die's versatility and durability. By moving the expander ball to the rear when a crimp is needed, you can back the bullet out without dragging it through the entire case neck. This means less wear on your cases—a real advantage if you're building ammunition over multiple reloading cycles. The arrangement of both pilot and seating stem on the same side of the case neck ensures smooth, concentric operation as the die cycles, reducing friction and allowing you to seat to the limit of the case neck rather than fighting resistance through its full length.

This is a demo/used unit, so you're getting a genuine Redding seating die at a practical price point. If you're building a .450 Bushmaster rifle load and want the precision tooling that professionals trust, this Series C seating die belongs in your press.

Frequently Asked Questions

What makes a Series C seating die different from standard seating dies?

The Series C uses a separate bottom punch that seats the case body to the shoulder, rather than seating through the entire case neck. This design reduces friction, minimizes case neck wear, and delivers better long-term accuracy—especially important for military and target ammunition.

Can I use this die to reload both crimped and non-crimped rounds?

Yes. When you need to apply a crimp, the expander ball moves to the rear and the bullet backs out the rest of the case. If you're loading non-crimped ammunition, you can seat without the crimp step, taking full advantage of the reduced friction the design provides.

Is this die compatible with my reloading press?

This is a Redding Series C seating die sized for .450 Bushmaster straight wall cases. It will fit standard reloading presses that accept Series C dies. Verify your press's die compatibility before purchase if you're uncertain.
