Redding 300 Winchester Magnum Bushing Full Length Type S Die

The Redding 300 Winchester Magnum Bushing Full Length Type S Die brings precision case resizing and neck control to your reloading bench in a single operation. If you're loading for a magnum rifle and want the flexibility to manage case neck concentricity while resizing the body, this die delivers the level of control serious handloaders expect from Redding's Type S platform.

What sets the Type S design apart is its adjustable decapping rod and interchangeable bushing system. The bushing self-centers on the case neck, improving concentricity naturally—no secondary operations required. You can dial in exactly how much of the neck gets sized with each press stroke, which means you're not over-working cases or creating unnecessary runout. The included standard size button and decapping pin retainer give you everything needed to get started, and the die accepts any of Redding's compatible bushings for neck sizing precision across other calibers.

Redding Type S Full Length dies also convert to body-sizing function by removing the bushing and internal parts, which adds flexibility if your reloading needs shift down the road. For 300 Winchester Magnum hunters and precision rifle shooters who understand that case prep is as important as powder charge, this die handles the repetitive work while maintaining the concentricity and consistency that separate good ammunition from great ammunition.

Frequently Asked Questions

What's the difference between a Type S bushing die and a standard full length die?

Type S dies let you resize the case body for consistency while the bushing handles the neck independently. That means you control how much neck sizing happens and can match the neck to your specific chamber, improving concentricity and reducing case runout compared to a standard full length die that sizes the entire case uniformly.

Can I use different bushings with this 300 Winchester Magnum die?

Yes. The die accepts Redding's interchangeable bushing system, so if you reload other calibers with Type S dies, you can swap bushings between them. You'll need to purchase bushings separately for other calibers.

What happens if I remove the bushing—does this die still work?

When you remove the bushing and internal parts, the die functions as a body die, resizing only the cartridge case body. This gives you flexibility if your reloading workflow changes or you want to segregate neck sizing to a separate step.

Does this come with everything I need to start reloading 300 Win Mag?

The die includes the body, a standard size button, and a decapping pin retainer. You'll still need a compatible press, shell holder, powder measure, primers, powder, bullets, and cartridge cases to complete your reloading setup.
