Redding Series A Taper Crimp Die for Straight Wall Cases .38 Spl /.357 Mag

If you're reloading .38 Special or .357 Magnum for revolvers and semi-autos, the Redding Series A Taper Crimp Die gives you precise, consistent case mouth control without the aggressive deformation of a roll crimp. This specialized die is built for straight-wall handgun cartridges where headspace depends on the case mouth—a critical detail for safe, accurate reloads. The taper crimp method applies gentle, uniform pressure that seats the bullet firmly while preserving cartridge overall length, so you get reliable feeding and consistent velocities without compromising case life.

Reloaders who value uniformity and repeatability choose taper crimp dies over conventional roll crimps because they produce more consistent bullet pull and require less force at the press. If you're loading for match shooting, defensive carry, or precision revolver work where every round needs to perform identically, this die delivers the control you need. Steel construction means it'll handle thousands of reloads without wear.

The Redding Series A line is known for holding tight tolerances and delivering the kind of precision that matters when your handloads are going downrange. Whether you're a serious revolver shooter or someone who appreciates the repeatability of a well-engineered reloading die, this tool earns its place on your bench.

Frequently Asked Questions

What's the difference between a taper crimp die and a roll crimp die?

A taper crimp applies graduated pressure that gently tapers the case mouth inward, holding the bullet firmly without aggressive deformation. A roll crimp uses more force and leaves a pronounced roll at the case mouth. Taper crimps are gentler on cases, preserve overall length, and deliver more uniform bullet pull—making them ideal for handgun ammunition where consistency matters.

Can I use this die for both .38 Special and .357 Magnum?

Yes. This Redding die is designed for straight-wall cases and works with both .38 Special and .357 Magnum cartridges.

Is the taper crimp die suitable for semi-auto handguns?

Yes. This die is designed for handguns with headspace on the case mouth, including both revolvers and semi-automatic pistols.
