Lock-N-Load® Modified Cases
Modified Cases are readily available to fit most popular rifle chambers.
All are manufactured to SAAMI specs. 
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.
Straight Model 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.
Curved Model 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
