This forum has little to do with precision and more to do validating consumer choices. The overwhelming majority of serious precision shooters have nothing to do with this forum (and criticize those of us who do).
Look at precision shooting sports and roles for your answer:
Benchrest, TR, F-Class, Match Rifle and the role of the sniper involve a firearm that is capable of putting a round exactly where you want it to go, as many times as you need it to go there.
A Precision rifle is only part of the equation - like a race car.
Benchrest is about achieving the smallest possible groups. If everyone used hunting rifles, then the requirements would be quite different. They shoot some zero-sized groups - that is 5 shots through the same hole. No factory gun shooting factory ammo is going to achieve that.
F-Class needs to put strings of up to 20 shots into a .5MOA v-bull at distances of up to 1000M. That does NOT mean it takes a .5MOA rifle, it takes a shooter who is capable of reading conditions, match ammo AND an accurate gun.
TR is shot off the elbows and needs a rifle to be accurate, for it is the shooter that is the weak link.
These require the right action, the right barrel, the right stock for the ergonomics of the sport, the right optics and the right load. On top of that it takes skill and practice. Skill does not come from practicing with a rifle that is incapable of precision.
A competitive shooter would learn nothing by "practicing" with a hunting rifle in between shooting seasons. You will never develop your full potential as a shooter, or your load developing skills if you have a gun that is incapable of producing optimal results.
One lesson so many ignore here is that you get what you pay for.
