The Lee Collet Crimp Die in .500 S&W Magnum (Lee part no. 90931) applies a rifle-style collet crimp to straight-wall .500 S&W Magnum cases, giving hard-recoiling revolver loads a firmer hold on the bullet than a standard taper or roll crimp alone. Because the collet forms its own crimp as it closes around the case mouth, the bullet does not need a dedicated crimp groove machined into it, which is a real advantage for handloaders running heavy magnum loads where bullet pull under recoil is a genuine concern. This is not a carbide die, so cases should be lubricated per Lee’s standard instructions before running them through the press.

Key Specifications

• Uses a collet-style crimp mechanism instead of a standard taper or roll crimp.
• Bullets do not need a crimp groove or cannelure for the collet to form a firm hold.
• This die is not carbide, so case lubrication is required before sizing/crimping.

Frequently Asked Questions

Is this die carbide? No, this Collet Crimp Die is not carbide, so cases need to be lubricated before running them through it.

Why use a collet crimp on a revolver cartridge? It locks the bullet down more firmly than a standard crimp, which helps prevent bullet pull under heavy recoil in magnum .500 S&W Magnum loads.
