It seems like some barrel manufacturers are somewhat quirky about barrel fluting. Some won't do it at all. Others will only flute certain contours. I have thought about ordering the barrel I want and just having a gunsmith do the fluting work. Here are my questions: 1. Can fluting harm the accuracy potential of a given barrel blank? 2. Does it matter when in the production cycle the fluting is cut? 3. If a barrel is fluted post-production, are there additional operations that are advisable (stress relieving or cryo treatment, for example)? I am asking this because I recently acquired a sporter weight .300WM with a VERY thin barrel contour. It feels so nice to carry, but the barrel heat walks severely after the second shot (and it is generously free-floated), feels like you could cook an egg on it after the third shot, and the rifle is light enough that it smacks me around pretty good. I would like to go with a barrel just heavy enough to mitigate recoil a bit and remain stable through a single 3 shot string. I am thinking a fluted #4 profile barrel would do the trick, but such an animal is not offered in the make of barrel that I want. If it is a practical idea to order the barrel and have a gunsmith do the fluting work, I would like to go that route. I just want to be aware of any pitfalls inherent in doing so.
