The RCBS 18212 Carbine 3-Die Set Group B is a complete reloading die set built for .357 Magnum and .38 Special handgun ammunition. Whether you're a target shooter, lever-gun hunter, or handloader who shoots both calibers from the same brass, this three-die setup handles the full sizing, expanding, and seating cycle—all without the fiddling of lubrication thanks to carbide components that let you work faster and cleaner.
RCBS developed the three-die concept specifically for straight-wall pistol and rifle cases, and it's a workhorse design that's been proven by thousands of handloaders. The carbide sizer die dimensions and de-primes in one pass, eliminating the need to lube your brass beforehand. The expander die opens the case mouth to proper diameter and imparts the slight flare (bell) needed for smooth bullet feeding. Finally, the seater die places the bullet at the correct depth and applies a roll crimp for reliable chambering and consistent velocity.
If you already have a press and shell holder, this die set gives you everything else you need to begin loading or reload. The Group B designation refers to RCBS's die compatibility grouping, so verify your press and accessories align before ordering. Handloaders who work with .357 Magnum for hunting, self-defense, or sport shooting, or who blend .38 Special target loads on the same equipment, will appreciate the simplicity and repeatability of a dedicated, matched die set.

Frequently Asked Questions
Can I use this die set in any reloading press?
The RCBS 18212 is a Group B die set. Your press and shell holder must be compatible with Group B dies. Verify your press specifications before purchasing. If you are unsure of your press compatibility, contact us or check your press documentation.
Do I need to lubricate my brass with these dies?
No. The carbide sizer die eliminates the need for case lubrication, which speeds up your reloading process and keeps your hands and workspace cleaner than with traditional steel dies.
What is included in the 3-die set?
The set includes the carbide sizer die (which also de-primes), the expander die, and the seater die. You will need a reloading press, shell holder, and reloading components (primers, powder, and bullets) to complete the ammunition-loading process.
Can I reload both .357 Magnum and .38 Special with the same die set?
Yes. This die set is designed for both .357 Magnum and .38 Special, since they share the same straight-wall case dimensions. You can load both calibers using the same dies, though you may need different shell holders depending on your press design—check your equipment manual.
