Hornady Lock-N-Load Modified Case 6mm ARC Rifle Brass

The Hornady Lock-N-Load Modified Case is a precision reloading tool designed specifically for use with Hornady's Lock-N-Load Precision gauges. Cut to exact 6mm ARC SAAMI chamber specifications from brass, this modified case lets handloaders verify their rifle's chamber dimensions before developing accurate loads.

Unlike standard reloadable brass, this case is specially machined with a fine thread that allows it to be securely attached to a Hornady Lock-N-Load Precision gauge. The result is a chamber-specific tool that replicates the dimensions of a fired 6mm ARC case, giving reloaders the reliable measurements they need to dial in neck tension, bullet seating depth, and overall length for their particular rifle.

Manufactured to SAAMI specs and built from brass to match the geometry of a fired case, the A6MMA is an essential bench accessory for any serious 6mm ARC handloader working with a Lock-N-Load Precision gauge system.
