New member and first post here. Was wondering what any of you knew about the 550 Magnum. I stumbled on one of the rifles on Gun Broker. It was based on the CZ550 receiver. Since then I have been trying to research it, since it looked like something I would be capable of building. Unfortunately, I find a lot of old posts but nothing very recent. Dis this rifle fade away or is it still out there being made? I'm not even sure if there is a maker. The original website lists sources for barrels, dies, brass and such. Some of these sites are no longer up. Not a lot of information out there. Anyone have any experience with it?
