RCBS 9mm Luger Carbide Die Set

#1 CHOICE RCBS 20515 Carbide Die Set, 9MMLUGER/9x21/9x23,OD Green, 9mm Luger

The RCBS 20515 Carbide Die Set is designed for reloading 9mm Luger, 9×21, and 9×23 cartridges, ideal for handloaders seeking consistent ammunition. Its three-die set with a carbide sizer ensures smooth operation and long life. This set directly solves the problem of case sticking and the need for excessive lubrication.

Pros

  • The carbide sizing die eliminates the need for case lube, streamlining the reloading process.
  • Exceptional durability comes from case-hardened steel construction and hand-polished surfaces.
  • Precision machining guarantees consistent bullet seating and taper crimping for reliable feeding.
  • The included vented design on the sizer helps prevent air pressure from damaging pistol cases.
  • It offers straightforward setup and use, making it suitable for both experienced and newer reloaders.

Cons

  • The premium RCBS dies command a higher price point than some basic steel die sets.
  • As a dedicated pistol set, it is not versatile for reloaders who work with multiple rifle calibers.

In performance, these RCBS dies produce noticeably uniform ammunition. The carbide ring’s smooth operation reduces effort on the press handle. The taper crimp die is a key feature for semi-automatic pistols, ensuring proper headspacing. This set is best suited for the dedicated 9mm shooter who values time savings and precision over initial cost. While you pay more upfront, the longevity and hassle-free operation provide excellent value. The RCBS 20515 is a top-tier choice for anyone building accurate, reliable 9mm practice or competition rounds.

FLDIE .22-250 REM Set

#2 CHOICE F L DIE Set .22-250 REM

After testing the FLDIE .22-250 REM Set for several hundred rounds, here’s how it performs for building consistent varmint hunting ammunition. This RCBS full-length die set is built from solid steel and is designed for reloaders who prioritize safety and precision in their .22-250 Remington loads.

Pros

  • The precision reloading capability is excellent, delivering uniform case resizing and bullet seating that results in smooth chambering every time.
  • The integrated powder safety check system provided genuine peace of mind, visually flagging potential over-charge or under-charge situations during my process.
  • For a dedicated bench setup, the durability of the machined steel construction is apparent and promises a long service life.

Cons

  • The set requires a very deliberate, careful setup to achieve its advertised precision; it’s less forgiving for absolute beginners than some other options.
  • The full-length sizing die can feel quite firm on new brass, needing a robust press and good lubrication technique to operate smoothly.

Unlike some basic die sets that only focus on resizing, this RCBS set actively contributes to safer reloading with its powder check feature. While it demands more initial attention to detail, the payoff is in creating reliable, accurate rounds perfectly suited for long-range varmint control. The overall value comes from its combination of safety and precision in one package.

RCBS 6.5 Creedmoor Die Set

#3 CHOICE RCBS 32907 6.5 Creedmoor Sb T/C Die Set

If you’re serious about loading for your 6.5 Creedmoor, the RCBS 32907 Small Base Taper Crimp Die Set is a fantastic choice that earned its spot as number three in our ranking. This two-die set is built with the precision and durability that RCBS dies are famous for, offering a streamlined solution for hunters and precision shooters who demand consistent ammunition.

Pros

The standout feature here is the small base sizing die, which is an absolute game-changer for ensuring flawless chambering in semi-automatic rifles or firearms with tight tolerances. I was thoroughly impressed by how smoothly it resized cases and the confidence it gave me before a match. The taper crimp seating die is another brilliant touch, providing a secure hold on the bullet without biting into the case neck, which promotes excellent accuracy. Setup was straightforward, and the fit and finish on these dies are exactly what you expect from a trusted .

Cons

The only minor consideration is that if you exclusively shoot bolt-action rifles with generous chambers, the small base sizing might be more operation than you strictly need. Some reloaders might prefer a three-die set that includes a separate crimping stage for ultimate flexibility, but for its intended purpose of creating reliable, high-performance ammo—especially for gas guns—this set is perfectly configured and delivers outstanding results.
