Overview
The Hornady Lock-N-Load Headspace Comparator Kit is an indispensable reloading tool designed for serious reloaders seeking to maximise brass life, enhance accuracy, and ensure optimal safety in their ammunition. This precision headspace gauge kit allows you to accurately measure critical variations in your brass before and after firing or resizing, providing the essential data needed to achieve consistent, high-performance ammunition for hunting and sporting activities.
Achieving optimal reloading performance, particularly with full-length resizing, hinges on precisely adjusting your die to set the case shoulder back by .001" to .002". Guided by the comparator's readings, this meticulous adjustment ensures minimal clearance within your firearm's chamber. Correct headspace is paramount: it significantly minimises case stretching, reduces work hardening, extends case life, and directly contributes to superior accuracy and overall safety. This process is fundamental for any reloader committed to crafting refined and reliable ammunition.
- Precision Brass Measurement: Accurately measures variations in brass before and after firing or resizing, enabling direct comparison between fire-formed and resized cases for optimal die adjustment.
- Enhanced Reloading Safety: Helps identify excessive headspace conditions, promoting reliable primer ignition and consistent load performance for increased safety.
- Extends Case Life: Proper headspace settings minimise case stretching and reduce work hardening, significantly prolonging the usable life of your valuable brass.
- Improves Ammunition Accuracy: Precise die adjustments, informed by comparator readings, create minimal chamber clearance, leading to improved shot-to-shot consistency and accuracy.
- Bent Rim Detection: Autoloader users can easily identify cases with bent rims by rotating the brass, helping to eliminate inconsistent shots or "flyers" and maintain load integrity.
- Wide Cartridge Compatibility: Includes five interchangeable bushings compatible with most bottleneck cases, from .17 Rem through large belted magnums, offering comprehensive support for Ackley Improved chambers.
