The Redding Taper Crimp Die for .223 Remington (MPN: 85111) is a precision-machined, heat-treated alloy steel reloading die designed to secure .224" diameter projectiles in .223 Remington and 5.56×45mm NATO cartridge cases. Unlike traditional roll crimp dies that fold the case mouth inward and risk buckling case necks or distorting bullet jackets, this die applies uniform, angled pressure directly along the case mouth. It establishes consistent neck tension and cartridge retention for match and hunting bullets manufactured without an external crimping cannelure, preventing projectile setback during cycling and magazine feeding.

  • Non-Cannelure Bullet Retention: Applies a controlled taper crimp that secures plain-shank .224" diameter bullets without deforming jackets or crushing brass shoulders.
  • Alloy Steel Construction: Precision-machined from heat-treated alloy steel to maintain tight internal dimensional tolerances over high-volume reloading cycles.
  • Standard Press Mounting: Uses an industry-standard 7/8"-14 thread interface to ensure compatibility with standard single-stage, turret, and progressive reloading presses.
  • Feed Reliability: Eliminates case mouth flare and provides consistent neck grip to prevent bullet movement under recoil in magazine-fed firearms.

Who is the Redding Taper Crimp Die for .223 Remington for?

  • High-volume semi-automatic .223 Rem shooters — Secures .224" diameter bullets against recoil-induced projectile setback during rapid cycling by applying a uniform taper crimp across 7/8"-14 threaded reloading setups.
  • Reloaders loading non-cannelure bullets for magazine-fed rifles — Delivers smooth, reliable chambering in .223 Remington and 5.56×45mm NATO chambers by closing the case mouth precisely around non-cannelured .224" diameter projectiles without buckling the case neck.

Less suitable for: Precision bolt-action shooters achieving sufficient neck tension without crimping, handloaders seating bullets with deep grooves who require a mechanical roll-crimp die or collet-style factory crimp die, or reloaders needing fast on-press adjustments who would be better served by a micro-adjusting taper crimp die featuring an external micrometer top.
