Hornady Lock-N-Load 300 Rem Ultra Mag Modified Case, 1 Count

Hornady Lock-N-Load 300 Rem Ultra Mag Modified Case, 1 Count


Modified case for 300 Rem Ultra Mag.



These cases are specially modified to work with Lock-N-Load Precision gauges. 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.
