How do I know whether my rifle is long action or short action?

Long action Savage magazines measure approximately 3.5″ long. We produce magazines for the .25-06, .270, .30-06, and .300 Winchester Magnum calibers in this action length.

Short action Savage magazines measure approximately 3″ long. We produce magazines for the .308 family of cartridges (including the .243, .260, and 7mm-08 calibers) and the 6.5 Creedmoor in this action length.
