The .243 Winchester, developed and introduced by Winchester in 1955, is a popular rifle caliber derived from the .308 Winchester case necked down to accept a .243 inch diameter bullet. As a result of its design, the .243 Win. offers a combination of high velocity, flat trajectory, and mild recoil, making it an attractive choice for a wide range of shooting activities.

Technically, the .243 Winchester typically delivers muzzle velocities between 2900 to 3200 fps depending on bullet weight and powder charge, with common bullet weights ranging from 55 to 105 grains. The most popular weights, especially for hunting purposes, tend to be in the 80 to 100 grain range. Lighter bullets, typically around 55 to 70 grains, are often used for varmint hunting, providing high velocity and explosive impact on small game.
