I look at this process as a way of telling the person what the rifle is capable of, "NOT" the shooter.
If you know what your rifle will do, then you can try/work on getting your shooting skills up to the quality of your rifle. (Very few can shoot as well as when they use a rest of any kind) and this is the reason for bench testing.
When building a accurate rifle, normally a Maximum MOA is required and to prove this accuracy standard is reached some form of bench testing is done. Then when the customer receives his/her rifle they know what "IT" will do. and not what they can do but it does give them something to strive for.
Most are very happy to know that there rifle is that accurate even if they cant shoot to the level of there rifle. I always want my rifle to out shoot me because it makes me a better shooter and because I have no one or nothing to blame except my self if the shot is not spot on.
An accurate rifle is no less accurate when someone hunts with it, only the shooters ability can make up the difference.
Just My Opinion
