Redding Premium Handgun Die Set For Straight Wall Cases - .45 Colt

The Redding Premium Handgun Die Set for Straight Wall Cases in .45 Colt is purpose-built for reloaders who demand consistency and durability when working straight-wall pistol cartridges. This three-die set pairs a Titanium Carbide sizing die with a newly engineered expander die and a precision seating die, giving you the control needed to produce ammunition that shoots the way you loaded it.

The standout feature is Redding's expander plug, now coated in Titanium Nitride (TiN) for superior hardness, lubricity, and wear resistance. The TiN coating cuts down on brass buildup—a real win for high-volume reloaders running .45 Colt through a progressive press. The expander itself is engineered with a purpose: a radiused base eases entry, a parallel section expands and trues the case for a consistent bullet bearing surface, a small step aligns the bullet to centerline, and a final flare accommodates cast bullets without shaving lead during seating. That level of geometry matters when you're after uniformity.

The seating die comes equipped with a bullet seating micrometer for repeatable, precise seating depth control. Whether your .45 Colt load calls for a taper or roll crimp, this die handles it. All three dies feature enhanced lead-ins designed to feed smoothly in progressive presses, so you're not fighting geometry when you're trying to stay in rhythm.

Frequently Asked Questions

What's included in this Redding .45 Colt die set?

The set contains three dies: a Titanium Carbide sizing die, an expander die with TiN-coated expander plug, and a seating die equipped with a bullet seating micrometer for depth control.

Will this die set work in my progressive press?

Yes. All three dies feature enhanced lead-ins designed for smooth feeding in progressive reloading presses, though they are equally compatible with single-stage presses.

What does the TiN coating on the expander plug do?

The Titanium Nitride coating adds surface hardness, improves lubricity, and increases durability. It also reduces brass buildup on the expander—a practical advantage if you reload high volumes of .45 Colt.

Can I use this set to load cast bullets?

Yes. The expander plug includes a flare stage at its tip to further open the case mouth, which helps prevent shaving lead when seating cast bullets.
