Came up with 40 RWS cases for my 6.5x58R barreled drilling...but need Berdan primers (I'm guessing RWS 4520 but still researching). Are there any sources of small rifle Berdan primers...or have they gone the way of the Dodo bird?

Thanks

You could contact these guys and see if they can get SR, they have LR.
