The Lee Precision 7.62x54R Collet Neck Sizing Die (brand part no. 91637) sizes only the neck of fired 7.62x54R brass, squeezing the case neck against a precision mandrel instead of running the whole case through a sizing ring. That keeps body dimensions fire-formed to your own chamber, which most handloaders chasing accuracy in bolt guns want. Lee Precision designed this collet system to work without case lubricant, and because it only touches the neck, brass sees less working per firing and lasts longer between anneals. It’s a natural fit for precision rifle handloading where consistent neck tension matters more than full-length resizing every time.

Key Specifications

• Sized specifically for 7.62x54R brass, matching the case neck diameter for that cartridge only.
• Collet fingers squeeze the case neck against a precision mandrel, sizing the neck without running the case body through a sizing ring.
• No case lubrication is required, unlike a conventional full-length steel sizing die.
• Sizes only the neck, which reduces brass working per firing and typically extends case life versus full-length sizing every time.
• Well suited to precision rifle handloading where minimizing runout and preserving fire-formed body fit matter.
