Don't get me wrong, I'm all for having the best money can buy and I can afford when it comes to the rifle and the ammo. But, the modern day produced rifle out-of-the-box is typically pretty damn good. I will invest in a custom rifle or two in the (not near) future, because I want to eventually get to a point where I can and do shoot more rifle sports. But, like everything shooting, if you are not putting pills down range, you simply have a very expensive custom status symbol.
Reliabily shoot approximately 1/2 MOA and built to do the job is my minimum for shooting long distance. From there, cost per quality is exponential. Practice can overcome a lot as long as the minimum quality requirements are filled, but if you settle on the minimum your whole life, you will never reach your true potential in shooting.
