Hornady Lock-N-Load Modified Case .300 Winchester Short Magnum

Achieve precise bullet seating depth.

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.

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

FEATURES:

• Works with Hornady  Lock-N-Load® O.A.L. Gauge.
• Manufactured to SAAMI specs.
• Fits .300 Winchester Short Magnum.
  
• Accurate to .001".
