The Hornady Lock-N-Load Modified Case in 221 Remington Fireball (brand part no. A221) is a specially modified case built to work with Hornady’s Lock-N-Load Precision gauges. A fine thread is machined into the case so it attaches securely to the gauge and stays perfectly square for precise alignment in the chamber. The case neck is made perfectly round and opened slightly so a standard-diameter bullet slips into the case mouth effortlessly while staying concentric, which is what makes gauge readings repeatable and trustworthy. Reloaders using Hornady’s precision measuring tools for 221 Remington Fireball need this modified case to get accurate seating-depth and headspace readings.
