I have a Shilen Select Match on my Rem 700 25-06. With hand loads it's a 1/2 moa rifle. However, it was not my first choice and my smith contacted a friend of his at Shilen to have the barrel made for me. I have seen several rifles with Shilen barrels that didn't group worth a crap. I doubt I will ever purchase another of their products based on what I have seen of their work. Even the smith that built my 25-06 was not enthusiastic about using a Shilen, but couldn't find another barrel in stock that was available.
Take a look at Benchmark, McGowan, and Lothar Walther if you want a quality button rifled barrel at a fair price. If money is not an issue then get a Bartlein, Rock, Krieger, Obermeyer, Broughton or Brux. I've had at one point or another a barrel from all of the above and they all shot or shoot as good as any. In fact, I can hardly tell the difference between any of them. They all clean up with little or no elbow grease, and all of them shoot better than I do. As stated above, I recommend buying the blank contoured and fluted to your specs, then have a good smith that knows his craft chamber, crown, and install the barrel.
