Description
The .32-40 Winchester is one of those old-timer cartridges that's tough to keep on the shelf, so if you shoot an 1885 Highwall, a Winchester 94, a Marlin, or one of the reintroduced single shots, handloading is really the way to feed it. This RCBS Group D full-length 2-die set is built specifically for the .32-40 and gives you the two tools you need to turn fired brass into fresh, accurate ammo.
What the .32-40 Win Die Set Does on the Bench
The set pairs a full-length sizer die with an expander-decapping unit and a separate seater die with a bullet seater plug. The sizer brings your brass back to SAAMI minimum dimensions, resizes the outside of the case, punches out the spent primer, and expands the neck to accept the next bullet, all in one stroke. Vent holes in the sizer let trapped air and excess lube escape so you're not denting shoulders or crushing cases. RCBS holds headspace to minimum tolerances so the case body length stays put during sizing, which matters when you're stretching brass life on a cartridge that isn't easy to replace.
Seating and Crimping Your .32-40 Loads
The seater die uses an adjustable bullet seater plug to dial in your seating depth and overall length, and it has a built-in roll crimper to lock the bullet in place as it seats. That roll crimp is handy for the .32-40 since a lot of these rifles run tube magazines where a solid crimp keeps things secure under recoil. The dies use the standard 7/8-14 thread, so they thread right into any common press.
RCBS Quality You Can Count On
RCBS has been making reloading gear in Oroville, California since 1943, and these dies are cut from hardened steel and hand polished for the kind of durability that lasts decades. Just remember you'll need the correct shell holder and case lube to get rolling, since neither ships in the box.

Frequently Asked Questions
Does the RCBS .32-40 Win die set come with a shell holder?
No, the shell holder is sold separately and is not included in this set. RCBS builds their die sets this way so you can match the correct shell holder to your press and brass. You'll want to pick one up along with case lube before your first sizing session.
What comes in this Group D full-length die set?
You get two dies: a full-length sizer die with an expander-decapping unit and a seater die with an adjustable bullet seater plug. The sizer resizes the case, removes the spent primer, and expands the neck, while the seater sets your bullet depth and applies a roll crimp. Together they cover the core steps of loading .32-40 Winchester ammo.
Will these dies fit my reloading press?
Yes, the dies use the industry-standard 7/8-14 thread, so they thread into RCBS presses and virtually any other common single stage or turret press. That standard sizing makes them easy to swap in and out of your setup.
Do I need to lubricate my brass with this die set?
Absolutely, case lube is a must for full-length sizing bottleneck brass like the .32-40. Skipping lube can stick a case in the die, which is a headache to remove. A light, even coat of sizing lube before you run cases through the sizer keeps everything moving smoothly.
