But judging a hunting rifle from a bench next to a bench rifle is not really fair.
I don't care how good of groups your heavy, long barreled, 12lb rifle with 16 adjustments on the stock is capable of throwing at the range off of bags and 10 minutes of setting up. Its never going to replicate those hunting where a bench is not available.
Your right my, for instance, M77 is never going to throw as good of groups off the bench as that theoretical bench rifle is. BUT that theoretical bench rifle is not going to be halfway up the mountain taking a shot off an improvised rest after tracking and moving after a herd of elk all day.
Hunting accuracy IS different than bench accuracy and is dependent, to some degree, on the shooter.
