Featured Products
Our flagship product, the Hornady AP Progressive Press Reliability Kit, is engineered to transform the performance of your Hornady AP press. While the AP is a solid platform, many reloaders experience persistent issues with case feeding, station alignment, and overall consistency — especially when running high volumes. If you’ve ever questioned whether you should have gone with the “blue” press, or you’re tired of dealing with jams, spilled powder, and crushed cases, this kit is designed for you.
Developed specifically for high-volume reloading of 9mm, .40 S&W, and .45 ACP, our reliability kit enhances the AP’s smoothness, precision, and repeatability, enabling you to produce hundreds — even thousands — of rounds without interruption. Every component was refined through extensive engineering, testing, and real-world use to deliver a dramatically more dependable reloading experience.
To maximize your reliability results, please see the details outlined in the Additional Info section below.
