Re: ER Shaw barrels- Anyone use them????
They are often referred to as "tomato stakes", and while that may be a little harsh, I would never recommend investing in one if there is custom 'smithing involved, since you're spending a lot in labor for something that may render mediocre results.
They are clearly budget barrels and perhaps a good value <span style="font-style: italic">for the money</span>, but a little more money will get you something consistently and predictably accurate. If I was paying George or Jared to re-work a rifle for me, I'd never ask them to use one and they'd probably refuse anyway.
That said, I bought a discounted short-chambered 26" .308 barrel from a friend and installed it myself on a secondhand 700 VS that shot like crap with everything it was fed. I finished off the short chamber with a Palma '95 reamer at .002" headspace and it shoots FGMM 175s VERY well, "surprisingly well" even. I often get groups under 1/2 moa, and get enough of them that I would take the blame for those that don't make it. Looking at it with my borescope, I cannot figure out how it shoots at all, but it's not a lot worse than most of the Remingtons I've looked into.
