Product Summary
The Hornady Powder Bushing 420 is an essential component for the 366 Auto Progressive Shotshell Press, designed for precision fine-tuning of your shotshell loads. These bushings are machined from solid bar stock and reamed to ensure high-quality performance and durability. A key safety feature is the interchangeable design, which prevents shot and powder bushings from being accidentally reversed in the charge bar. For optimal results, it is recommended to purchase the specific bushing size along with the next size higher and lower. Always use an accurate scale to verify powder weights, as actual weights may vary from chart listings.
