🔍 Overview

Federal Champion No. 155 Large Magnum Pistol Primers are designed for heavy handgun loads that require hotter, more powerful ignition. These magnum primers are essential for cartridges using slow-burning powders or large case capacities, such as .44 Magnum, .454 Casull, and .45 Colt +P.

They deliver consistent, hot ignition needed for magnum-level performance, especially in hunting, self-defense, or competition settings.
