45 Super* is the same externally as the 45 Auto, but has a thicker web, denser grain structure in the metal, and special heat treat process that enhances the durability of the case. Similar internal capacity as the 45 Auto. Some 45 Super load data was published by Triton Cartridge before they went out of business. *Loads to be shot ONLY in guns modified professionally to handle extreme pressures of this cartridge. DO NOT SHOOT IN STANDARD 45 AUTO!
* Starline Brass does not sell any loaded ammunition. What you are purchasing are brass cases only and will need to be loaded into ammunition in order to be fired from a firearm.
