Lee Collet Neck Die .22-250 Rem

Lee Collet Neck Sizer Die for .22-250 Remington

The Lee Collet Neck Sizer Die represents a straightforward approach to one of reloading's most critical operations: preparing case necks for consistent bullet seating.

How It Works

Instead of the traditional sizing button found in conventional dies, Lee's collet system uses a precision mandrel that is squeezed by a collet. This design creates a precisely aligned case neck while dramatically reducing runout—the wobble that occurs when a bullet isn't perfectly centered in the case.

Key Features

• Collet-based design squeezes the case neck against a precision mandrel
• Minimal runout ensures bullets are seated concentrically for better accuracy
• No lubrication required simplifies the reloading process
• Neck sizing only preserves case life by avoiding full-length sizing
• Ideal bullet seating provides consistent shot start pressure comparable to crimping

Why This Matters

For handloaders pursuing maximum accuracy, the Lee Collet Neck Sizer Die ensures your bullets are seated with the proper fit and alignment. The mandrel design allows you to seat bullets far enough that they touch or nearly touch the rifling, establishing the ideal shot start pressure without additional crimping.

This die is built for precision-minded reloaders who understand that consistency in case preparation directly translates to tighter groups downrange.
