List of Winchester Center Fire rifle cartridges.More commonly known as WCF, it is a family of cartridges designed by Winchester Repeating Arms Company. [1] There are many other Winchester cartridges that do not carry the WCF moniker, such as the .300 WSM. .270 Winchester, and .300 Winchester Magnum
In 1925, Winchester introduced the .270 Winchester, previously known as the .270 WCF, based on the 30-03 Springfield case necked down to .277" (6.8 mm).

Performance with a 130-grain (8.4 g) bullet is approximately 3,405 ft/s (1,038 m/s) and with a 150-grain (9.7 g) bullet is approximately 3,250 ft/s (990 m/s).
These bullets include most Barnes' bullets over 110 gr (7.1 g) and any conventional spitzer bullet of over 115 gr (7.5 g).

Velocities tend to be about 250 ft/s (76 m/s) faster, in a cartridge that is ...

The .308 x 1.5" case is available from a number of case manufacturers and differs from a ...
