The Redding Series C Neck Sizing Die for 6mm GT (part no. 81199) gives precision rifle handloaders a neck-only option for bottleneck 6mm GT brass, resizing just the case neck instead of the full case body. Neck sizing preserves more of the fire-formed fit between the case and a specific rifle’s chamber, a technique competitive shooters use to extend brass life and improve consistency. It requires Shell Holder #1, sold separately, to operate on the press.

Frequently Asked Questions
