My Brother has a 50 BMG heavy rifle built on a single shot EDM action.  I believe he told me it was called an SA1.  Does this sound familiar to anyone who knows about early EDM products, and what can you tell me about them?  I am guessing as a 50 cal, other long distance calibers in 375,408, and 416 would  all fit this action?  I am looking at buying it from him, or at least helping him sell it, and would like to know as much as I can find out.  My searches for EDM all come back with the Windrunner M96.  Any help you can give me would be greatly appreciated.
