Military-grade ammunition manufactured at a Missouri facility has been used in at least a dozen mass shootings from AR-15-wielding assailants across the US within the last decade, with its shell casings recovered at the scene of some of America’s deadliest massacres.
Ammunition from the Lake City Army Ammunition Plant, which has manufactured nearly every rifle cartridge used by the US military within the last 50 years, is also one of the largest manufacturers of commercial rounds for AR-15-style rifles, the most popular firearm in the US.
