Description

The .32-20 Winchester is one of those old-school cartridges that refuses to fade away, and finding quality brass for it can be a chore. Starline solves that problem with their .32-20 unprimed cases, sold here in a bag of 100 fresh, ready-to-prep pieces. These are virgin cases built for small pistol primers, measuring roughly 1.280 to 1.286 inches in length, so you have a touch of room to trim to your preferred spec before loading.

Why Starline .32-20 Brass Earns Its Keep

Starline has built a long-standing reputation among reloaders for consistency, and that reputation holds up across forums and review pages. People regularly point to the uniform primer pockets, tight wall tolerances, and the way the brass resizes cleanly without a fight. The brass also tends to hold up over multiple firings when you keep your loads sensible, which matters a lot when you are feeding an older or harder-to-find firearm. For a cartridge that first showed up back in 1882, having a modern, dependable brass source is a real win.

Loading the .32-20 for Rifles and Revolvers

The .32-20 Winchester, also known as the .32 WCF, was originally a lever-action round and later found a home in Colt single-action revolvers. That dual personality is exactly why this brass is so handy. It works for both the rifle crowd and the sixgun shooters, and it has become a favorite in cowboy action and period-correct shooting circles. The bullet runs a .312 to .3125 inch diameter, and the case is a rimmed, slightly bottlenecked design, so take your time with case lube and die setup to keep things smooth.

A Starting Point for Wildcats and Conversions

One of the quiet perks of this .32-20 brass is its versatility beyond the factory chambering. With the right forming dies, experienced cartridge converters use it to create .25-20 and .218 Bee cases, and with specialty dies you can even form a shortened 7.62 Nagant case. If you enjoy the hands-on side of reloading, this gives you a solid foundation to work from.

Frequently Asked Questions

What primer size does Starline .32-20 Winchester brass use?

These cases are built for small pistol primers. That is the standard primer size for the .32-20 Winchester, so pick up a quantity of small pistol primers to match your load. Always verify against your current reloading data before you prime.

Can I use this .32-20 brass in both rifles and revolvers?

Yes. The .32-20 Winchester was originally a lever-action rifle round and was later chambered in single-action revolvers like the Colt. This brass works for both, which is a big part of why it stays popular with cowboy action and period-correct shooters.

Is this brass primed or ready to shoot?

No, these are unprimed cases, not loaded ammunition. You will need to prime, charge with powder, and seat a bullet before they are ready to fire. They come fresh and unfired, so a quick inspection and trim to your preferred length gets them ready to load.

Can Starline .32-20 brass be formed into other cartridges?

It can, with the right tooling and some experience. Cartridge converters commonly form .32-20 brass into .25-20 and .218 Bee, and with special forming dies you can create a shortened 7.62 Nagant case. If you are new to case forming, start with proper dies and go slow.
