Which calibers are long action and which are short action?

Table of contents


There are a number of resources that provide complete specifications and dimensions of rifle calibers. 


The Sporting Arms and Ammunition Manufacturers' Institute (SAAMI) is an association of the nation's leading manufacturers of firearms, ammunition and components. SAAMI was founded in 1926 at the request of the federal government and tasked with:

  • Creating and publishing industry standards for safety, interchangeability, reliability and quality
  • Coordinating technical data
  • Promoting safe and responsible firearms use


Cartridges of the World by Frank C. Barnes is another excellent resource for detailed information on cartridges, history, and dimensions.
