Specially modified 6mm ARC case with threaded head and .002" oversized neck for use with Hornady Lock-N-Load Precision gauges. Manufactured to SAAMI specifications for precise reloading measurements.
The Hornady Lock-N-Load Modified Case represents a thoughtful solution for reloaders who demand precision. This case is specifically engineered to work with Hornady's Lock-N-Load Precision gauges, allowing you to measure overall cartridge length with accuracy to within .001".
The modified case threads onto your Lock-N-Load gauge, holding it perfectly square in relation to your firearm's chamber. The slightly enlarged neck allows you to insert the exact bullet you plan to load, giving you a true measurement of overall length. This eliminates guesswork and helps you achieve consistent, safe ammunition.
Use the same bullet diameter you intend to load in your finished ammunition. The gauge itself and dial calipers are sold separately. This is a precision tool for serious reloaders who understand the value of accuracy.
