About this item

Achieve precise bullet seating depth. Use the Hornady Lock-N-Load Modified Cases along with the Hornady Lock-N-Load O.A.L. Gauge (sold separately), to fit your firearm's chamber and thread it onto the gauge. These specially prepared modified cases are threaded at the case-head and have a .002" oversized neck to accept the same bullets you intend to load. This is critical, as the Lock-N-Load O.A.L. Gauge dimensions obtained will be accurate to .001". These results cannot be attained with competitive products, which use a simulated bullet with an arbitrary shape. Hornady Lock-N-Load Modified Cases are readily available to fit most popular rifle chambers. All are manufactured to SAAMI specs. Hornady Lock-N-Load Modified Cases are specially modified to work with Lock-N-Load Precision gauges. A special fine thread is used on this Hornady reloading tool to attach it to the gauge, ensuring that it remains perfectly square for precise alignment in the chamber of your firearm.
