Lock-N-Load O.A.L. Gauges

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.

Product Line

The Lock-N-Load® O.A.L. Gauge is universally acclaimed as the most accurate, easy-to-use and reliable method of regulating seating depth and the resulting "jump" to the rifling.

Straight Model

Item #C1000

For all bolt-action and single-shot firearms, or any firearm with straight-line access to the chamber. This model is preferred, as it is most precise and user friendly.

Item #C1550

For all autoloader, lever-action, or pump-action rifles. Also fits all bolt-action and single-shot firearms. Inserts into chamber through ejection port. Not compatible with Adapter "D" or short-bodied cases.
