Description
The Redding 458 SOCOM Full Length Die Set covers the two jobs that matter most when you're loading this hard-hitting big-bore cartridge: resizing your brass back into spec and seating your bullet with precision. It's a two-die set that pairs a full length sizing die with a standard seating die, both machined to the tight tolerances Redding has been known for since 1946. The sizing die works the full length of the case and knocks out the spent primer in the same stroke, while the decapping rod assembly carries a neck expander button to open up case mouths for smooth bullet seating.
What Comes With the Redding 458 SOCOM Die Set
The seating die includes a bullet guide, a built-in crimping ring, and the correct seating plug for the 458 SOCOM, so you can dial in a crimp when you want one, which is handy on a cartridge that sees stout recoil and benefits from solid bullet tension. Redding builds these dies from fine alloy steels and machines them on precision lathes, which is a big part of why reloaders trust them for accurate, repeatable ammo.
Getting Started With Your 458 SOCOM Reloading Dies
One thing worth knowing up front: the shell holder is not included. For the 458 SOCOM you'll want a #1 shell holder (Redding part 11001), the same one used for 308 Winchester, 30-06 Springfield, and 45 ACP, so there's a good chance you already have one on the bench. The dies use the standard 7/8-14 thread and drop right into any common single stage or turret press.
If you're shooting a 458 SOCOM AR and tired of paying factory prices for ammo, rolling your own is where the real value kicks in. This set gives you a clean, no-nonsense starting point for building consistent handloads with whatever bullet and powder combination your rifle likes best.

Frequently Asked Questions
Does the Redding 458 SOCOM die set come with a shell holder?
No, the shell holder is sold separately. For the 458 SOCOM you'll need a #1 shell holder, which is Redding part number 11001. That same shell holder also works for 308 Winchester, 30-06 Springfield, and 45 ACP, so many reloaders already own one.
What dies are in this 458 SOCOM full length set?
You get two dies: a full length sizing die and a standard seating die. The sizing die resizes the whole case and removes the spent primer, while the seating die has a bullet guide, a built-in crimping ring, and the proper seating plug to set your bullet and apply a crimp if you want one.
Will these dies fit my reloading press?
Yes, the dies use the industry-standard 7/8-14 thread, so they thread into any common single stage, turret, or progressive press. Just pair them with the correct #1 shell holder and you're ready to load.
Can I crimp 458 SOCOM rounds with this seating die?
You can. The seating die includes a built-in crimping ring, so you can apply a roll crimp when it's time to seat your bullet. A solid crimp is helpful on the 458 SOCOM since it helps keep bullets in place under recoil and in tube-fed or magazine-fed setups.
