Hornady Lock-N-Load® Modified Case

Hornady modified cases are specially modified to work with Lock-N-Load Precision gauges such as the OAL Overall Length gauge. The special fine thread at the base is used to attach the case to the gauges, ensuring that they remain perfectly square for precise alignment in the chamber of your firearm.

The neck of the case is perfectly round and opened slightly to allow a standard diameter bullet to slip into the case mouth easily but concentrically.
