There are three lengths of action (not including the Model Seven's lightweight action, which is even shorter than the 'standard' short action). There is the short action for cartridges up to 2.800 in (71.12 mm) in overall length like the .308 Winchester cartridge family, the standard action for cartridges up to 3.340 in (84.84 mm) in overall length like the .30-06 Springfield and .300 Winchester Magnum cartridge families and the long action for magnum calibers exceeding 3.340 in (84.84 mm) in overall length like the .300 Remington Ultra Magnum and .375 Holland & Holland cartridge families.
