The 7mm Winchester Short Magnum (WSM) was introduced along with the 270 WSM in 2002. Case length is 2.100-inches, allowing it to be housed in most short bolt actions, yet the efficiency of its short, fat case allows performance very similar to the 7mm Remington Magnum. Despite obvious value the 7mm WSM has not yet become popular, perhaps as a combined result of the large number of unbelted magnums introduced in a short period; and the large number of fast 7mm cartridges on the market. Whether popular or not, the 7mm WSM is an accurate and effective cartridge, suitable for any purpose one might envision for the 7mm Remington Magnum.
