Lee Precision 90818 Factory Crimp Die 22-250 Rem/22-250 AI

The Lee Precision 90818 Factory Crimp Die delivers consistent bullet seating depth and case mouth crimping for both 22-250 Remington and 22-250 Ackley Improved cartridges. This specialized reloading die eliminates the variables that cause accuracy problems by applying uniform crimp pressure to each case.

What Makes This Different

Unlike standard seating dies that can over-crimp or under-crimp depending on case length variations, the Factory Crimp Die uses a collet system that adapts to individual case dimensions. The die crimps into the cannelure or crimping groove without affecting overall cartridge length. This dual-caliber compatibility covers both the standard 22-250 Remington and the fire-formed Ackley Improved variant with a single tool.

Key Features

• Collet-style crimping system adapts to case length variations automatically
• Compatible with both 22-250 Remington and 22-250 Ackley Improved cartridges
• Standard 7/8-14 thread pattern fits most single-stage and turret presses
• Hardened steel construction with precision-machined internal components
• Includes detailed instructions for proper setup and adjustment
• Works with all bullet weights and styles commonly used in 22-250 applications
• No case length trimming required for consistent crimping results

The Factory Crimp Die proves particularly valuable for high-velocity cartridges like the 22-250 where bullet pull consistency directly impacts accuracy. Varmint hunters appreciate the reliable ignition and consistent velocities this die produces across different lot numbers of brass. Competition shooters benefit from the reduced velocity spread that comes with uniform case mouth tension.
