Description

Starline 500 S&W Mag R Brass (100)

In July of 2003, Smith & Wesson and Cor-bon changed specification of primer pocket to be large rifle. Rifle primers are same diameter as pistol but are approximately .006″ taller. This was done to prevent primer from being pierced by firing pin when loaded with max loads and heavy bullets (bullets over 400 grains). It was determined that a pierced primer could allow pressure to damage firing pin and bushing; the harder cup of a rifle primer will prevent this occurrence. All 500 S&W Mag cases manufactured by Starline after July 28, 2003 will contain a large rifle primer pocket to accept a large rifle primer. Hodgdon Powder has generated load data which recommends using Winchester Large Rifle Primers.

Cor-bon has also tested and recommends CCI 250 primers (Magnum Large Rifle). New Starline 500 S&W Mag cases will have an “R” after the “Mag” on head stamp to signify rifle pocket. If you have previously purchased 500 cases without “R” on head stamp and wish to modify, you can use a large rifle pocket uniformer to deepen primer pocket to accept large rifle primers by deepening pocket approximately .006″. This will not affect integrity of case. For concerns regarding this situation contact Smith & Wesson or Cor-bon as they designed case and subsequently changed it.
