Lee 90735 Factory Crimp Rifle Die 6.8mm Remington SPC

The Lee 90735 Factory Crimp Rifle Die for 6.8mm Remington SPC is a specialized reloading die designed to deliver the firm, consistent bullet seating that separates match-grade handloads from good-enough ones. If you're loading 6.8 SPC for precision work—whether competitive shooting, long-range hunting, or load development—this die addresses a real accuracy problem: loose bullets that shift under firing pressure, causing velocity and point-of-impact variation. Lee's Factory Crimp Die works differently than a standard seating die; it uses a collet mechanism that squeezes the case mouth into the bullet's crimp groove (or creates a firm hold even on bullets without a groove) after the bullet is seated, locking it in place before firing.

The mechanics matter here. When a bullet isn't firmly crimped, pressure has to build higher before it overcomes bullet runout and starts to move in the case. This delay creates an uneven pressure curve and measurable velocity spreads—exactly what kills accuracy at distance. Lee's approach ensures pressure starts building consistently the moment firing begins, producing the uniform velocity and tighter groups that serious reloaders chase. Tests demonstrate that even bullets designed without a crimp groove will shoot more accurately with a firm crimp applied by this die.

Compatible with all standard 7/8"-14 threaded reloading presses (the industry standard for single-stage and progressive loaders), the die threads directly into your press without modification. Note that a shellholder is not included—you'll need the correct Lee shellholder for 6.8 Remington SPC to complete the setup. This is a single-purpose tool: add it to your 6.8 SPC die set after your sizing and seating dies are dialed in, and you'll notice tighter velocity nodes and more predictable downrange performance.
