What Makes Hornady Lock-N-Load Cartridges, .300 Blackout, – 1 out of 20 models Stand Out?
The Hornady Lock-N-Load Cartridge Gauge in .300 Blackout is a deceptively simple tool with the potential to save reloaders significant time, frustration, and even prevent catastrophic firearm damage. Hornady, a name synonymous with quality ammunition and reloading components, brings their expertise to this essential piece of kit designed for ensuring proper cartridge dimensions. This gauge promises to eliminate guesswork and ensure consistent, reliable ammunition, making it a vital addition to any serious .300 Blackout reloader’s bench.
I’ve been reloading for over a decade, primarily focusing on precision rifle cartridges. While I hadn’t initially considered a cartridge gauge essential for pistol rounds, my foray into .300 Blackout subsonic loads for an AR pistol changed my perspective entirely. The need for consistent, reliable feeding in a short-barreled AR platform, combined with the tight tolerances required for subsonic performance, led me to seek out a more precise method for verifying cartridge dimensions.
Upon unboxing, the gauge felt solid and well-made. The Hornady Lock-N-Load Cartridge Gauge exudes quality with its high-carbon steel construction. The weight lends confidence and suggests it will withstand years of use.
Compared to a simple case gauge, this tool aims for a higher degree of precision. While a case gauge simply indicates if a cartridge fits within general SAAMI specifications, the Hornady Lock-N-Load intends to flag more subtle inconsistencies. I chose this over a cheaper, less precise gauge from an unknown brand because I trust Hornady’s reputation for quality control and accuracy.
My first impression was one of cautious optimism. The Hornady Lock-N-Load Cartridge Gauge seemed like a well-engineered solution to a frustrating problem. I was excited to put it to the test and see if it lived up to the claims of improving reliability and consistency.

First Use Experience
I tested the Hornady Lock-N-Load Cartridge Gauge primarily at my reloading bench, focusing on a batch of .300 Blackout cartridges intended for suppressed subsonic use. I was preparing for a hog hunt and wanted to ensure optimal performance. I utilized the gauge after completing the resizing and seating stages of my reloading process.
The Hornady Lock-N-Load Cartridge Gauge delivered as promised, ensuring consistency in the rounds I tested. Performance was unaffected by ambient conditions within my reloading space, as the testing was conducted indoors. I found the Hornady Lock-N-Load Cartridge Gauge remarkably easy to use.
There were no real surprises or immediate issues with the gauge itself. However, using it highlighted some subtle inconsistencies in my reloading process that I hadn’t previously detected.
