If you know anyone in your area that can cryo-freeze the barrel and action, someone who will actually do the job, give it a try! I have had several rifles cryo-ed in the last few years, and I swear by it. It really gets rid of and "thrown" shots from a hot or even cold barrel groups. It costs 35$ here for it to be done, I also use Moly in the barrel and on my rounds, I don't know if it helps accuracy, but it will keep you from having to clean after you shoot, and it doubles your barrel life.
