The question of whether ammunition manufactured by Prvi Partizan (PPU) employs corrosive primers is a common concern among firearm enthusiasts. Corrosive primers contain chemicals, such as potassium chlorate, that leave salts behind after firing. These salts attract moisture and can cause rust and pitting in the bore if not removed promptly. Non-corrosive primers, on the other hand, produce less residue and are generally considered safer for firearms in the long term.
Understanding primer corrosivity is crucial for proper firearm maintenance. Historically, corrosive primers were widespread due to their reliability and cost-effectiveness. However, with advancements in ammunition technology, non-corrosive primers have become the standard. Proper cleaning procedures after using ammunition with corrosive primers involve removing the residual salts with specialized cleaning solutions, followed by regular cleaning and lubrication. Neglecting this process can significantly reduce the lifespan and accuracy of a firearm.
