Hornady Lock-N-Load Modified Case for OAL Gauge

Achieve precise bullet seating depth

These cases are specially modified to work with Lock-N-Load OAL Gauges (sold seperately). A special fine thread is used to attach them to the gauges, ensuring that they remain perfectly square for precise alignment in the chamber of your firearm. Second, the neck of the case is made perfectly round and opened slightly to allow a standard diameter bullet to slip into the case mouth effortlessly, but concentrically, to ensure the most precise results possible.
