Winchester subsonic ammunition is probably the best selling .22LR vermin control cartridge in the UK. It is quiet and accurate making it the first choice for many shooters who lamp, use night vision or just don't want to draw unwanted attention.
Winchester owes its humble beginnings to Rimfire Ammunition. As a matter of fact, Winchester's first commercially available metallic cartridge ammunition was a large calibre rimfire load introduced back in 1866. More than 130 years later, rimfire is the world's most popular ammunition. As you would expect, Winchester has you covered with a complete line of high-performance cartridges. From precision target shooting to plinking, small-game hunting and silhouettes, Winchester is chosen by rimfire shooters worldwide.
