Lyman Stainless Pro Carbide Sizing Die - 38 Super

The Lyman Stainless Pro Carbide Sizing Die for 38 Super brings serious durability to your handgun reloading bench. If you're pushing volume on a progressive press or just tired of fighting rusty steel dies, this stainless steel carbide sizing die cuts down friction, eases case alignment, and lasts through thousands of rounds without the corrosion headaches of traditional tooling. Built on Lyman's pioneering carbide technology, the Pro version pairs a stainless steel body with highly polished carbide sizing rings—a practical upgrade for reloaders who want their dies to stay in service for years.

The real work happens in the carbide ring itself. That polished surface dramatically reduces the force needed to size cases, which means less wear on your press and smoother operation whether you're loading one box or a thousand. The mouth of the ring has a generous radius that lets cases seat easily and square up on progressive equipment, cutting down on cross-threaded or damaged brass. A spring-loaded decapping rod system handles primer pocket ejection reliably, every single round—no surprises, no primers hanging up.

Stainless steel construction means no rust developing on your die after a humid season or a few months of lighter use. For reloaders in damp climates or those who store their equipment for stretches between sessions, that's a genuine quality-of-life improvement. The carbide ring's wear resistance keeps your sizing consistent round after round, which translates to better chamber fit and more predictable ballistics downrange.

Frequently Asked Questions

Will this die work on my progressive press?

Yes. The generous radius on the carbide ring mouth is specifically designed to allow cases to align easily on progressive equipment, making it a good fit for high-volume loading setups.

Why choose carbide over steel sizing dies?

Carbide rings reduce the force needed to size cases, which puts less stress on your press and brass. They also resist wear far longer than steel, keeping your sizing consistent through thousands of rounds. Combined with the stainless steel body, you get durability without corrosion issues.

Does this die include a decapping rod?

Yes. The die is equipped with a spring-loaded decapping rod system designed to ensure primers are forcefully ejected from the primer pocket reliably on every stroke.

What makes stainless steel better than standard steel for a reloading die?

Stainless steel resists rust and corrosion, so your die stays in good condition even if stored in humid conditions or left unused for extended periods. You avoid the maintenance hassle and potential scoring of corroded dies.
