Smith and Wesson Model 1
Yes, Winchester did create a prototype .22 caliber revolver, known as the Winchester Model 1890, which was primarily a rifle. While the company is more famous for its rifles, there were experimental revolvers developed in the early 20th century, but none went into full production. These prototypes are rare and of interest to collectors, but Winchester is not widely known for .22 caliber revolvers.
No, a .22 caliber CCI22s bullet, which is a type of .22 Short ammunition, cannot be used in a standard .22 caliber Ruger revolver unless the revolver is specifically designed to accommodate .22 Short cartridges. Most Ruger revolvers are chambered for .22 LR (Long Rifle) cartridges, which are longer than .22 Short cartridges. Always check the specifications of the firearm and use only the appropriate ammunition for safety.
