The Lee Precision .204 Ruger collet neck sizing die is built for reloaders who want tighter case neck concentricity and longer brass life without fuss. Unlike full-length sizing dies, this neck-only die uses a precision steel collet to squeeze your fired case neck down to a mandrel, aligning it true while keeping body runout to a minimum. That means better accuracy downrange and cases that'll last through more reloads before they're done.
Because this die sizes only the neck—not the entire case—you won't need to lube your brass before sizing. That saves a step and keeps your press cleaner. It's designed to work best with cases fired through your own rifle, where you already know the fire-formed body dimensions.
If you're handloading .204 Ruger for precision rifle work, competition, or any application where case neck runout matters, a collet die like this one is a smarter choice than full-length sizing. It preserves case dimensions more carefully and lets you reload the same brass many more times with consistent, repeatable results.

No. Because this die sizes only the neck, case lubrication is not required. That's one of the advantages of neck-sizing over full-length sizing.
This die is designed to work best with cases that have been fired through your own firearm. Factory ammunition or brass fired in other rifles may have different body dimensions and may not size reliably.
The steel collet squeezes the case neck onto a precision mandrel, aligning it concentrically and reducing runout. Better neck runout means more consistent bullet seating and more uniform bullet release, which translates to tighter groups and more reliable accuracy.
Neck sizing preserves the case body, reducing the working and stress cycling that shortens brass life. By sizing only the neck, you'll extend the lifespan of your cases through many more reloading cycles compared to full-length sizing.
