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 Gauge is universally acclaimed as the most accurate, easy-to-use, and reliable method of obtaining that critical relationship.
To use the OAL Gauge you will need to purchase a Modified Case to fit your firearm’s chamber and thread it onto the Gauge. Stoney Point offers interchangeable Modified Cases in all common sizes from .17 Remington up to and including .45 Government. These specially prepared Modified Cases are threaded at the case-head and have a .002″ oversized neck to accept the same bullets you intend to load. This is critical – as the OAL Gauge dimensions obtained will be accurate to .001″. Results such as this cannot be attained with competitive products which use a simulated bullet with an arbitrary shape.
The OAL Gauge has a lightweight bullet push-rod, molded from tough glass-filled nylon. It provides improved sensitivity and position-holding reliability. It will also fit prior model (straight) OAL Gauges, for an easy upgrade.
C-1000 Straight Model: 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.
