Hornady Custom Grade Series II 3-Die Pistol Set .357 Sig .355"

The Hornady Custom Grade Series II 3-Die Pistol Set for .357 Sig is built for reloaders who demand precision and reliability from their handgun ammunition. This three-die set gives you everything needed to efficiently reload .357 Sig cartridges (.355" diameter), whether you're working up loads for competition, practice, or duty use. Hornady's Custom Grade dies represent the premium tier of the reloading die lineup—hand-inspected and hand-polished to exacting standards so you get smooth, consistent operation every time you pull the handle.

The standout feature here is the non-slip Zip-Spindle design, which locks the spindle with confidence and keeps your dies perfectly aligned during sizing and bullet seating. That matters when you're chasing tight groups or building ammo for a carry gun—misalignment introduces variables you don't want. And because these dies don't require case lube, you'll spend less time prepping brass and more time at the press or range. The polished surfaces aren't just for show; they reduce friction and make each stroke smoother, which adds up over thousands of rounds.

If you're already set up with a compatible single-stage or progressive press, this three-die set slots right in. It's the kind of equipment that pays dividends through consistency and longevity—Hornady's reputation in reloading rests on attention to detail, and you see it in every polished surface and tight-fitting component.

Frequently Asked Questions

What press will this die set work with?

This three-die set is compatible with standard single-stage and progressive reloading presses that accept standard .355" diameter pistol dies. Check your press manual to confirm the die mounting standard.

Does this come with everything I need to start reloading .357 Sig?

The three-die set includes the dies themselves. You'll also need a compatible reloading press, shell holder, and the usual reloading consumables (brass, primers, powder, bullets). Die sets do not include a shell holder or press.

Why don't these dies require case lube?

The polished surfaces and precision engineering of Hornady Custom Grade dies reduce friction during sizing, eliminating the need for case lubricant. This speeds up your prep process and keeps your workspace cleaner.

Is this set suitable for .357 Magnum as well?

No. This set is specifically designed for .357 Sig, which uses a .355" bullet diameter. .357 Magnum uses the same .357" bullet diameter but is a different cartridge case and requires its own die set.
