The Hornady C1550 Lock-N-Load O.A.L. Gauge eliminates guesswork when determining optimal cartridge overall length for maximum accuracy. This precision measurement tool works with multiple rifle calibers to help handloaders achieve consistent seating depth and improved performance.
What Makes This Different
Unlike basic calipers or improvised methods, the C1550 features Hornady's Lock-N-Load system for quick caliber changes without tools. The curved design allows easy access in tight spaces while maintaining measurement accuracy to within 0.001 inches. The red anodized aluminum construction provides durability while remaining lightweight at just 0.22 pounds.
