The .243 Winchester Super Short Magnum (.243 WSSM) was designed in 2003 by Browning and Winchester. It is based off the .300 Winchester Short Magnum cartridge and has a 1:10 twist with a large rifle primer. The ballistic performance of the .243 WSSM based off 5 grain types are 4,068 ft/s (58 gr), 3,707 ft/s (70 gr), 3,545 ft/s (80 gr), 3,280 ft/s (90 gr), 3,136 ft/s (100 gr). The cartridge is mainly used for varmint hunting, in addition to medium sized game such as deer.

Due to financial problems, Winchester shut down the rifle production plant for the .243 WSSM in 2006, but Browning picked up the rights for most of the Winchester rifle products. The .243 WSSM has a slightly higher velocity than the .243 cartridge that provides for a slightly bigger recoil on rifles. The rifles that were designed for the bullet were scaled down in weight that allowed for youths to be able to use as their first shooting rifle. The butt stock was not reduced to allow for a better length of pull though, so modifications by owners were needed to reduce the LOP on a shortened butt stock for youth shooters.

Olin owns the Winchester brand name for case manufacturing and produces all commercial market cartridges for the .243 WSSM. Hand loading brass can also be purchased through and Olin dealer. The .243 WSSM was made lighter and was used by but not originally designed for youth shooters. After Winchester shut down production in 2006 the .243 has virtually become obsolete on the market.
