Description

Hornady OAL Gauge goal is to measure the specific chamber and to develop your cartridge with a perfect seating depth calculations.

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.
A corresponding caliber modified case should be used with this gauge.
