The Redding 7mm TCU Bullet Seating Die (Heat Treated Alloy Steel) (MPN: 92242) is a dedicated reloading die designed to seat .284" diameter projectiles into the 7mm TCU (Thompson/Center Ugalde) wildcat cartridge. Machined from alloy steel that is heat-treated in atmospherically controlled furnaces and hand-polished, this standard seating die maintains precise cartridge overall length (COL) while resisting galling and wear. It features industry-standard 7/8"-14 TPI threading to interface with single-stage and progressive reloading presses, and includes an internal roll crimp profile that can be applied or backed off depending on press setup.

Key Features

  • Precise Projectile Seating: Incorporates an internal bullet guide and seating plug to align and seat standard .284" diameter bullets to consistent cartridge overall lengths.
  • Adjustable Roll Crimp: Built-in roll crimp feature allows reloaders to apply a crimp by adjusting die depth against the shellholder or back off the die to seat bullets without crimping.
  • Heat-Treated Alloy Steel: Precision-machined and furnace-hardened steel construction prevents galling and withstands extended reloading lifecycles.
  • Standard Thread Interface: Features 7/8"-14 TPI threads compatible with standard mechanical reloading presses.

Who is the Redding 7mm TCU Bullet Seating Die for?

  • Australian Thompson/Center Contender Handloaders — requires a 7/8"-14 TPI threaded 7mm TCU bullet seating die to seat .284" diameter bullets accurately into fire-formed 7mm TCU brass for single-shot pistol platforms.
  • Metallic Silhouette Handgunners and Specialty Rifle Shooters — needs consistent cartridge overall length using a dedicated 7mm TCU seating die with a built-in roll crimp to manage .284" projectile alignment for competition handloads.

Less suitable for: Handloaders seeking micrometer adjustments calibrated in .001" increments or straight-line floating sleeve alignment, who require a dedicated competition micrometer seating die, or those loading standard factory 7mm rounds like 7mm-08 Rem or 7mm Rem Mag, which require full-length dies machined specifically for those cartridge dimensions.
