Yes.
About 5 years ago I had them rebarrel my sendero to a 7mm stw. Reading article after article on barrel harmonics and weight and this and that I was looking forward to a very accurate barrel.
It wasnt, might as well had a shotgun it patterened so bad at 100 yards that I took the barrel off and bought a video from American Gunsmithing Insititute and replaced it with a Lilja and finally got my accurate barrel.
Yes they are cheap and at the time when I wanted my rifle in the STW caliber I didnt have the money to send it to Lilja or Shilen to get it rebarreled.
I wasted my money and time by going with E.R. Shaw. From what I've been told the rifling on their barrels is very shallow and the steel isnt of the same quality as some of the rest of the barrel makers i.e. Shilen, Lilja, Douglas, Hart, Pacnor and a few others.
I would not go with an E.R. Shaw barrel stick with what wins and one of the barrels I mentioned above.
