The .35 Whelen is a powerful medium-bore rifle cartridge that does not require a magnum action or a magnum bolt-face. The parent of this cartridge is the .30-06 Springfield, which is necked-up to accept a bullet diameter of .358 in (9.1 mm). This cartridge is more powerful than its parent, especially in killing power on large game. However, with much wider availability, and the higher BC (ballistic coefficient) .30 caliber bullets of today, the power gap between the two cartridges has been decreased.
