Research notes
This is the rimless version of the Gradle Express. It was developed during the 1950's by Roy Gradle of Santa Barbara, CA. The original cartridge was based on a heavily modified 348 Winchester case. Except for the rounded shoulder and slightly longer neck, it nearly mimmicks the 7mm WSM. There is a full article on the history of the 7mm Gradle Express in Rifle #248, (January 2010)
