RCBS Single Stage Shell Holder #45 - 5.7x28mm FN

The RCBS Shell Holder #45 is a precision-engineered reloading accessory built to hold 5.7x28mm FN cases in correct alignment during resizing and reloading. Designed and manufactured by RCBS, this numbered shell holder drops into any RCBS single-stage or turret reloading press to give the case a stable, repeatable position relative to the die.

Machined from hardened steel with a silver finish, the #45 captures 0.125 inch of the case head to meet SAAMI case-head dimension specifications, ensuring consistent shoulder setback, decapping depth, and priming alignment round after round. It is cut specifically for the small bottleneck case profile of 5.7x28mm FN ammunition and will not correctly hold larger or smaller cartridges.

Fully compatible with RCBS single-stage and turret reloading presses, the #45 is a straightforward upgrade or replacement for any 5.7x28mm reloading setup. Hardened-steel construction provides long service life even under repeated press cycles, and the simple drop-in form factor means there are no adjustments or calibration required - just seat the holder in the press, drop in your 5.7x28mm case, and run your die.
