The use and ownership of suppressors across the United States continues to grow in popularity. This growing popularity prompted Winchester to introduce a line of ammunition called Super Suppressed, made specifically for shooting through firearms outfitted with a suppressor. Super Suppressed ammunition launches projectiles at subsonic speeds to remain quiet when fired through a suppressor. Super Suppressed ammo also uses clean burning powders to leave less carbon and lead residue in your can. This ammunition is new production, non-corrosive, in brass cases.
