Accuracy is a relative thing . Your idea of acceptable accuracy and mine may not be close to the same .
And on the other hand you (figuratively) and I may shoot better or worse then one another .
And on the third hand I do not believe there to be a rifle that is bedded correctly with a usable trigger that i cannot work up a load for to give me acceptable hunting accuracy . I define acceptable hunting accuracy as three shots in 3/4" or less at 100 yards for a bolt action or Ruger #1 . For lever actions acceptable accuracy is three shots inside 1 1/2" at 100 yards.
Now my criteria is based on me shooting from a bench with a front and rear sand bag . I try to take me IE the shooter out of the equation when working up an acceptable load .
I am sure quite a few of you will say 3/4" isn't necessary and you are correct in that . However it does give one an added confidence factor especially if you take a few head shots each year .
