I have a Tikka T3X in 300 Win Mag that I would like to install a brake on. Straight from the factory, shooting handloads, it is extremely accurate. I consistently get <0.5MOA with multiple different bullets and powders. I have a couple of different gunsmiths that I use. They seem competent and they both build custom rifles, but I have never used them for anything more than a simple repair. Would it be reasonable to have one of them thread and install a brake or would you recommend shipping it off to a reputable smith? I would like the reduced recoil, but certainly don't want to mess up the accuracy. Also, what brake would you recommend?
