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.
