Hornady Lock-N-Load Modified Case – 7mm Remington Magnum (A7MMR)
The Hornady Lock-N-Load® Modified Case for 7mm Remington Magnum is a precision tool designed to work seamlessly with the Hornady O.A.L. Gauge system. It allows reloaders to accurately measure the Overall Length (O.A.L.) of their cartridges to achieve optimal bullet seating depth and consistent jump to the rifling—critical for precision shooting and load development.
🔍 Product Overview:
Each modified case is specially machined to SAAMI specifications and threaded at the case head to attach directly to the O.A.L. Gauge. The neck is slightly oversized to accept the bullet you intend to load, ensuring accurate and repeatable measurements that reflect your actual reloading setup.
