Yep, that makes it pretty much the same as a 500 A Square or a 500 Buhmiller. I'd go with the A2 myself, dies are more readily available. Have to get a throatless reamer and a .50 throater to chamber it though, if you want to shoot BMG bullets since the normal 500 A2 throat is too short. But I like to chamber and throat in two seperate operations anyhow.
