Hornady C1000 Lock-N-Load OAL Length Gauge (Straight)
- This tool allows re-loaders to quickly and easily determine the “proper” bullet seating depth in their firearm by accurately measuring their rifles free-bore.
ACHIEVE PRECISE BULLET SEATING DEPTH.
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 tackdriver
performance. The Lock-N-Load® O.A.L. Gauge is universally acclaimed as the most accurate, easy-to-use and reliable method of
obtaining that critical relationship.
To use the Lock-N-Load® O.A.L. Gauge, you will need a Modified Case (sold separately) to fit your firearm`s chamber and thread it onto the gauge. These specially prepared modified cases are threaded at the case-head and have a 0,0508 mm / .002″ oversized neck to accept the same bullets you intend to load. This is critical, as the Lock-N-Load® O.A.L. Gauge dimensions obtained will be accurate to 0,0254 mm / .001″. These results cannot be attained with competitive products, which use a simulated bullet with an arbitrary shape.
