The Redding 308 Winchester Taper Crimp Die (brand part no. 85155) applies a light taper crimp to seated bullets on 308 Winchester ammunition. Taper crimping is what most semi-auto rifle and pistol rounds need to feed and chamber reliably without setting the bullet back under recoil or magazine pressure. This die is sold individually to add a crimping step to a die lineup you already own.

Key Specifications

• It is chambered for 308 Winchester, applying a crimp sized to that cartridge’s case mouth.
• It applies a taper crimp, tapering the case mouth rather than rolling it, which suits cartridges that headspace on the case mouth.
• It is sold as a single die, meant to add a crimping station to a die lineup you already own.

Frequently Asked Questions

What’s the difference between a taper crimp and a roll crimp? A taper crimp gently tapers the case mouth inward without a lip, which suits cartridges that headspace on the case mouth, like most semi-auto rifle and pistol rounds. A roll crimp rolls brass into a bullet cannelure and is used on rimmed or heavy-recoil revolver cartridges instead.

Does this die replace my seating die? No. It’s a separate crimping die, used as its own station after the bullet has already been seated.
