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.
