The Hornady Lock-N-Load Modified Case, B Series .25 WSSM (Hornady part no. B25) is a specially prepared .25 WSSM case built to work with Hornady Lock-N-Load Precision gauges rather than being loaded and fired like standard brass. A fine thread at the case head lets it screw onto the gauge and stay perfectly square for an accurate reading. The neck is machined perfectly round and opened slightly beyond standard dimension so a bullet slips in smoothly and concentrically, which keeps the gauge measurement honest. Anyone measuring headspace on .25 WSSM needs the case that matches the chamber, and this is it.
