Hornady Custom Grade Series I 2-Die Set for .223 Remington (546228) - Precision Sizing & Seating

The Hornady Custom Grade Series I 2-Die Set for .223 Remington gives you the core tools for consistent, accurate handloads. This two-die set pairs a full-length sizing die with a bullet seating die, built with the precision and durability that have made Hornady a standard in reloading for decades. Whether you're fine-tuning loads for a precision rifle or keeping your .223 ammo performing at peak efficiency, this die set handles both the initial sizing and final seating in one compact package.

The sizing die features Hornady's Zip Spindle design, a cleverly engineered system that locks positively to prevent slippage while letting you make fine adjustments by turning the spindle or quick movements by zipping it up and down. Inside, smooth machining eliminates the friction and case sticking that can slow your workflow. The elliptical expander—Hornady's alternative to traditional ball expanders—sizes the neck more smoothly and with less stretch, and it's threaded internally so it won't pull loose during use.

The seating die uses Hornady's in-line bullet seating system, which aligns the bullet and case neck before the bullet ever touches the case mouth. A floating bullet alignment sleeve and floating steel seating stem keep everything centered for benchrest-grade consistency. The die includes a built-in crimper, so you can crimp as part of the seating stroke without eating up an extra press station. Seating depth adjusts easily with the adjustment screw, and a retainer ring comes off in seconds if you need to disassemble the die for cleaning.

Sure-Loc lock rings clamp fully around the die threads and tighten without ever contacting the threads themselves, eliminating the risk of cross-threading or damage from pliers. Both dies arrive in compartmentalized, stackable boxes that keep your reloading gear organized and easy to find. Hornady backs the set with a lifetime warranty against defects in materials and workmanship.
