You can't stress this enough. Face it, with modern CNC machining very rarely is the rifle to blame.
I used to get a chuckle when I worked in the shop and a shooter new to the distance game would come in and talk about buying a Surgeon, McMillan or buying a Remington 700 and dropping 1K having the barrel replaced and the action trued etc.
If you do you are just throwing away your money.
You are far better off spending that extra money on ammo and range time, then tweak your rifle as you improve and discover what improvements are actually needed/beneficial for your situation.
I used to liken it to wanting to drag race. You are not going to go out and buy a Top Fuel rail and learn with it and be competitive. You are going to start with a bracket car and work your way up.
