I have a BOTW Cooper in 6,5x284 and it has outstanding accuracy, consistent .25-.5", 5 shots measured at to 500 yards, some groups better! Hot, cold, clean, or dirty. My reloads or their ammo. The BOTW is not an out of the box Cooper, which are excellent shooters in their own right. They are basically a custom rifle
with speced barrels, perfectly bedded stocks, smoothed and worked actions, and thoroughly tested. Every aspect of this rifle will stand up against any custom out there, with impeccable workmanship. I was initially skeptical, and have been a very pragmatic, do it yourself person my whole life, but my wife wanted to get it for me for my 60th birthday. This rifle package was worth every penny, and the people at BOTW are great to work with, and truly experts at what they do. I recommend you call them, and get opinions from people that actually "own" one of their rifles IMHO.
