I have looked all over the web with no luck finding an answer. I have a E.R Shaw  24", 410 stainless steel, heavy bull barrel, 1/8 button rifled, with a 11 degree target crown. The barrel has had exactly 20 rounds down the pipe.  I am wanting a lighter 18" or 20" med weight barrel. I called ER Shaw and the number listed goes go voicemail with the standard "you have reached 412-221-3636" message,it  sounds like a cell phone recording.

probably get a good idea here
