If you run a suppressor on your .22 LR rifle or pistol, Winchester Super Suppressed ammunition is engineered specifically for you. This subsonic .22 LR load pairs a 45-grain copper-plated round-nose bullet with velocities kept below the sound barrier—the core feature that lets your suppressor do its job without the crack of supersonic flight. It's the quietest .22 you'll find without sacrificing the reliability and cleanliness shooters expect from Winchester.
The design cuts fouling at the source. The copper-plated bullet jacket fully encapsulates the core, which eliminates the lead vaporization inside your barrel and suppressor that turns into stubborn, hard-to-clean residue. That means your suppressor stays cleaner longer, your rifle cycles reliably shot after shot, and you spend less time at the bench with a brush. It's purpose-built for high-volume shooting—training, plinking, or zeroing—where you want consistent performance and minimal mess.
Comes packed 100 rounds per box, 20 boxes per case, so you can stock up for a day on the range or a full season of suppressed shooting. Clean-burning components deliver the consistency you need whether you're running a semi-auto or bolt gun. If noise management and barrel cleanliness matter to you, this is the .22 LR to run.
