Hornady Lock-N-Load 300 Winchester Short Magnum (WSM) Modified Case Gauge
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.
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. Hornady item # B300W
