Specially modified 22-250 Rem brass cases designed for use with Lock-N-Load Precision gauges. Threaded case head and .002" oversized neck ensure precise bullet seating and chamber alignment for accurate reloading.
Hornady's Lock-N-Load Modified Cases are engineered specifically to work with Lock-N-Load Precision gauges, giving you the accuracy tools you need for consistent, reliable ammunition.
When measuring overall length (O.A.L.) for your reloads, precision matters. These modified cases let you measure with the exact bullets you'll be loading, eliminating guesswork. The fine threading keeps cases perfectly square in the gauge, and the slightly opened neck allows bullets to seat concentrically—critical for achieving accuracy measurements accurate to .001".
These cases are designed specifically for gauging and measurement—not for firing. Use them with your preferred reloading gauge to establish precise O.A.L. dimensions, then apply those measurements to your regular ammunition. Dial calipers and gauges sold separately.
