Hornady Lock N Load 458 Lott Modified Case C458L

Regulating seating depth and the resulting ?jump? to the rifling is widely regarded as fundamental to improved accuracy. A few thousandths of an inch change between the bullet and the rifling can make the difference between average accuracy and real tack-driver performance. The Lock-N-Load O.A.L. Gauge is universally acclaimed as the most accurate easy-to-use and reliable method of obtaining that critical relationship. To use the Lock-N-Load O.A.L. Gauge you will need the Modified Case 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.
