I disagree. It's irrelevant how well it shoots strapped to a sled if you can't hit the target with it under actual field conditions.
Interesting point of view.
When I test for a rifles accuracy I use the most consistant method available at the distance
required ( 100 to 1000 Yards) depending the intended use.
This minimizes the human factor.(No two people will shoot the same) and once this accuracy
is determined it's up to the shooter to do his part.
There is no smith in the world that guarantees that the shooter can shoot 1/2 MOA, The rifle will
but not everyone can shoot 1/2 moa.
Most sportsman will admit that there custom rifle will out shoot them and that it gives them
confidence knowing that, And if they do there part it will be a good shot.
There are so many things that will effect the accuracy of a rifle and establishing a benchmark
for the rifle tells you when something has effected it.
Just my opinion
