Freedom Munitions ensures the quality of every round from start to finish. We develop and load all our ammunition (except .50 BMG) on our own Ammo Load Worldwide Mark X (pistol) and Mark L (rifle) systems. Placing an emphasis on premium components, we use X-Treme Bullets precision-swaged lead-core projectiles with full electrochemical copper plating — base included. Our process adds an extra re-strike of the plated cores to tighten diameter tolerances and produce a smoother, more uniform finish. The result is a U.S.-made projectile and cartridge built for reliable feeding, cleaner barrels, and repeatable down-range performance.. *Some discoloration may have occurred in these cases. Winchester WMA headstamped cases were purchased primed, new and unfired. They were factory sealed with a waterproofing lacquer in the case mouth and primer pocket. The discoloration is due to the annealing and added sealant, which we cannot remove from primed cases. Extensive testing has been done to ensure they are the same quality as any other case we use. A standard solvent is all that is needed to clean your firearm after use, and the cleaning process is the same for these as other unsealed cases.
