The RCBS Full Length Die Set, Group A, for 7mm TCU (brand part no. 34201) is a two-die set built for reloading this bottleneck cartridge popular with metallic silhouette shooters. The Full-Length Sizer Die includes an integrated Expander-Decapping Unit that sizes the case to SAAMI minimum dimensions while de-priming and expanding the neck to accept a new bullet, with vents built in to prevent case damage from trapped air or excess lube. Headspace is held to minimum tolerances so the case body length doesn’t change during full-length sizing, and the included Seater Die has a built-in roll crimper that secures the bullet at the same time it’s seated.
