This is NOT a piece of pipe. This is a professional blank that was gun drilled with only a few 1000ths run out. It is a 4140 alloy steel with great tensile strength. Drill your own flash hole and place trunnions.
Note: The metal has a thin layer of rust (most do) that is easily removed with one thin pass on the lathe. As this is hot rolled steel you will want to do this anyway.
