This Super Suppressed .22 LR 45-grain Lead Round Nose (part no. SUP22LRB2) is loaded specifically for suppressed rimfire shooting. The line is engineered for reduced noise, less barrel and suppressor fouling, and softer recoil compared to standard-velocity .22 LR, all built around a subsonic loading so a suppressor can do its job without a sonic crack from the bullet itself. The 45-grain bullet carries a black copper plating rather than bare lead, which helps keep fouling down in both the bore and the suppressor baffles over extended range sessions. Sold in a bulk 350-round box, it’s built for shooters who put a lot of rounds through a suppressed rimfire rifle or pistol.
