RCBS 3-Die Carbide Taper Crimp Die Sets are precision-made using proprietary steel. Each set includes a Carbide Sizing Die, Expander Die, and Bullet Seating Die for superior hand-loading performance.
RCBS pioneered and developed 3-Die Sets for straight-wall rifles and pistol cases. These sets for straight wall pistol cases build off of that legacy. Each set features a Carbide Sizing die that requires no case lube to speed up your sizing. The Expander die expands the case to the proper diameter to accept the bullet and also imparts case mouth flare/bell for easy bullet feeding. The bullet seating die then seats the bullet and puts on the appropriate crimp for the round being loaded.

FAQ
What's a taper crimp? What's a roll crimp? How are they different?
- A taper crimp gently straightens the case mouth to remove flare, making it ideal for semi-automatic pistol cartridges that headspace on the case mouth, like 9mm and .45 ACP. A roll crimp turns the case mouth into a bullet’s cannelure to firmly lock it in place, which is best for revolver cartridges that headspace on the rim and experience heavier recoil. RCBS typically offers one crimp style or the other for a given cartridge, however some cartridges such as 357 Mag/38 Special are offered in both roll and taper crimp.
What is a carbide die?
- A carbide die uses a polished carbide sizing ring inside the die body to resize cartridge cases, which eliminates the need for case lubrication during sizing. RCBS carbide sizer dies are designed primarily for straight walled pistol cartridges, making reloading faster, cleaner, and more efficient while still sizing and depriming the case in one step. The carbide insert greatly reduces friction and wear, allowing cases to size smoothly without lube and helping streamline high volume pistol reloading.
