Unprimed Brass Cases
500 S&W Mag Brass (Large Rifle primer)500 Smith & Wesson Brass, 500 S&W Brass, 500 Mag Brass
1.616 - 1.622 O.A.L.
The Initial run of 500 S&W Mag (R) cases was built to use large pistol primer per Smith & Wesson and Cor-bon specifications. On July 28, 2003, Smith & Wesson and Cor-bon changed specification of primer pocket to be large rifle. Rifle primers are same diameter as pistol except they 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 hole in primer allowed pressure to damage firing pin and bushing, kind of like a cutting torch and the harder cup of a rifle primer will prevent occurrence. All cases sold by Starline, Inc. 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 Win. Large Rifle Primers. Click here to view or call 918-251-5640.
Cor-bon has also tested and recommends CCI 250 primers (Magnum Large Rifle). Our new 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 situation contact Smith & Wesson or Cor-bon as they designed case and subsequently changed it.
*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.

This is quality brass at a good price, It stands up to the pounding this caliber gives it a lot better than other brands I used. I had other spit after 2 loading .not good with these guns. Plus cant beat the price. Starline my only when I buy new.

So I bought this brass about 2 years ago and I am now on my 15th reloading. I would say I have more than got my money worth out of this brass. I use HODGDON LILGUN and H110 powder and run it almost to max with a large magnum primer. Have not lost a case yet but I am starting to notice that the primer pockets are getting lose. I was expecting to get maybe 5 uses out of it but I who can complain about getting 15 uses out of the brass. Great job Starline! Will be ordering another box soon!

Excellent brass. The brass is up to par for heavy loads and I had no problems with it at all. I have used 350 gr, 500r, 400r bullets with different types of variations of loads and they all went bang. I trust Starline.

I have not had a case failure EVER, with this brass. I have loaded it at least 4 times with heavy loads.........it just goes back in the polisher, and to the press.
