HORNADY LNL Straight O.A.L Gauge C1000

Precisely regulating the bullet 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 just so-so accuracy and real tack-driver performance.

The OAL (overall length) Gauge is universally acclaimed as the most accurate, easy-to-use and reliable method of obtaining that critical relationship.
