Redding Dies are produced using precise manufacturing processes along with the highest quality components available.Body Dies are designed to full length resize the case body, bump the shoulder position for proper chambering, but not size the neck at all. They are made without internal parts and are intended for resizing cases which have become increasingly difficult to chamber after repeated firing. After using a body die, the case should be run through the neck die to achieve proper neck tension.
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 .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 .001". These results cannot be attained with competitive products, which use a simulated bullet with an arbitrary shape.
