Hornady LockNLoad OAL Tool – Straight
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 regulating seating depth and the resulting “jump” to the rifling.
Item #C1000For 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.
For this tool we recommend the Custom threaded cases. This means cases fired in YOUR rifle chamber should be prepared and threaded to use on this tool to give precise results.
