Overview
The Hornady Lock-N-Load Cartridge Headspace Gauge Bushing is an essential precision tool for serious reloaders, designed to significantly extend brass life, improve firearm accuracy, and enhance overall reloading safety. This individual bushing allows you to accurately measure critical headspace variations in your cartridge brass, both before and after firing or resizing. By enabling a precise comparison between fire-formed and resized brass, this component is fundamental for achieving optimal cartridge fit and consistent performance for hunting, target shooting, or general sporting use.
Using this bushing is straightforward when paired with the Hornady Lock-N-Load Headspace Comparator (sold separately) and a set of calipers. The bushing attaches seamlessly to the comparator, which then mounts to your calipers, enabling you to take precise measurements from the case head to the datum line on the case shoulder. This method provides a reliable way to monitor brass stretch and ensures you are resizing your cases correctly, preventing over-resizing which can lead to premature brass fatigue and potential chambering issues.
- Precision Measurement: Accurately measures critical headspace variations in cartridge brass before and after firing or resizing, enabling optimal cartridge fit and consistent performance.
- Compatibility: This A .330" bushing is compatible with a variety of popular calibres, including .17 Remington, .204 Ruger, .221 Remington Fireball, .222 Remington, .222 Remington Magnum, .223 Remington, and .220 Swift. Other Lock-N-Load Headspace Bushings are available to accommodate most bottleneck cases. For Ackley Improved chambers, the same bushing size as the parent case is utilised.
