Re: Tacticle action tolerances
I'll put in my two cents worth. After being a competitive shooter for 32 years now, plumbing guns for 27 years I know there are no absolutes. There are exceptions to every rule but here is what I've learned. No two Remingtons will perform the same, no two trued Remingtons will perform the same, not every custom action from the same maker will perform the same( they should but you get a wild one occasionaly I have a few along the way) i've had my own action for several years now, it's just a Remington clone but I know if I build 100 rifles, half trued Remingtons and half my action, the rifles built on my action will shoot better and be easier to tune up 90+% of the time.
Accuracy is a lot of small things that add up. Quality barrel, match chamber, any action that the ignition system works properly, decent stock and bedding job and bullets bullets bullets. Without 1/2 MOA bullets you'll never have a 1/2 MOA rifle then the other components will influence the package to varying degrees.
