The .17 Winchester Super Magnum (often abbreviated as .17 WSM) is a rimfire rifle cartridge that was introduced by Winchester in 2013. It was designed to provide a high-velocity option for small game hunting and target shooting.
The .17 WSM cartridge uses a 20 grain bullet, typically with a polymer tip, which allows for higher velocities and flatter trajectories than other rimfire cartridges. The cartridge has a case length of 1.2 inches and an overall length of 1.8 inches, which allows it to fit into standard rimfire rifles.
The .17 WSM cartridge is known for its high velocity, flat trajectory, and low recoil. It has a high ballistic coefficient, which helps it to retain its energy and velocity over long distances. It is also capable of delivering a significant amount of energy upon impact, making it an ideal choice for small game hunting and varmint control.
Ammunition for the .17 WSM cartridge is available from a variety of manufacturers, including Winchester and Hornady. It is available in a range of bullet weights and styles, including polymer-tipped and hollow point.
Overall, .17 WSM ammunition is an excellent choice for shooters who want a high-velocity option for small game hunting and varmint control. Its high accuracy, consistency, and versatility make it a popular choice among shooters of all levels of experience.
