I’ve been building .404 Jeffery rifles for over twenty years and the Lyman 17AHB is honestly the most consistent high die I've used. The tolerances are tight, which is exactly what you need for this specific caliber, though you definitely pay a premium for that precision.

Honestly, the 3171076 is a game changer for benchrest accuracy. The finish on the internal parts is mirror-smooth, which prevents any brass galling during the sizing process—worth every penny.

quality is fine but the packaging arrived crushed. the tool itself works but for this price i expected it to not look like it was kicked across the warehouse. kinda annoying but whatever.

Total waste of money for me. The threads were slightly off straight out of the box and it wouldn't seat properly in my press. Returning it immediately and going back to Redding.

Idk if I’d call it a "must have" but it’s definitely high quality. Its a bit more fiddly to set up than I expected, but once it’s dialed in, the consistency is there. Just be prepared to spend some time tweaking it.

I was skeptical about the price point at first, but after running 50 rounds through it, the concentricity is nearly perfect. If you're serious about your .404 Jeffery loads, don't skimp on the dies—get the Lyman.

I’ve been using Lyman gear for decades and this 3171076 .404 High is exactly what I needed for my latest custom Jeffery project. The consistency is top notch—honestly better than the custom dies I was using before. It’s definitely spendy, and maybe a bit overkill for a casual loader, but if you

Been reloading .404 Jeffery for thirty years and this Lyman 17AHB is the most consistent front sight height I've found for custom builds. It's pricey, yeah, but the machining is top notch and it saves me a lot of time at the bench.

The tolerances on the 3171076 are impressive. I’ve used cheaper alternatives in the past, but they always required a bit of filing to get perfect—this one was drop-in ready for my current project. Highly recommended for professional gunsmiths.
