The Hornady Lock-N-Load Modified Case, A Series, for 6mm Remington (Hornady part no. A6MM) is specially modified to thread onto Lock-N-Load Precision gauges for accurate seating depth and headspace measurement. A special fine thread attaches the case to the gauge and keeps it perfectly square for consistent readings, while the case neck is machined round and opened slightly so a standard-diameter bullet slips in effortlessly but stays concentric for the most precise results possible.
