The Lee Precision 5.7X28 FN full length sizing die is an essential tool for reloaders working with 5.7×28 ammunition. Unlike neck-sizing dies that only resize the neck portion of the case, a full length sizing die restores the entire cartridge case to proper dimensions after firing. This approach works across any rifle chambered in 5.7×28, making it the versatile choice for shooters who either reload for multiple rifles or want maximum case longevity and consistency.
When you fire a round, the brass case expands to fill your rifle's chamber. After extraction, the case contracts but rarely returns to factory dimensions. A full length sizing die corrects this by resizing both neck and body, while also removing any bulges or irregularities created during firing. The result is brass that chambers reliably and performs consistently across different rifles and shooting sessions.
Setting up the Lee die involves a methodical process: clean your fired cases, establish your baseline with a headspace comparator, then gradually adjust the die until the case shoulder is bumped back 0.001 inch. Proper lubrication and periodic checks—roughly every 10 cases—ensure your brass stays within spec and your press runs smoothly. Done right, full length sizing maximizes case life and prevents the work-hardening that leads to case head separation.

Yes. A full length sizing die is compatible with any rifle chambered in 5.7×28, regardless of manufacturer or action type. That's the primary advantage over neck-sizing dies.
A neck-sizing die resizes only the neck of the case. A full length sizing die resizes the entire case—both neck and body—restoring the cartridge to proper dimensions after firing. Full length sizing is more versatile if you reload for multiple rifles or want to ensure reliable chambering across different firearms.
This product is the sizing die only. A complete reloading setup typically includes a sizing die, a bullet seating die, a reloading press, and other components. Check your reloading manual and kit requirements to determine what else you'll need.
Check your shoulder bump every 10 cases or so and adjust the die if needed. Regular monitoring helps maintain consistency and prevents overworking the brass, which can lead to case head separation.
