I don't know anyone who shots with the same accuracy between their rifle shoot from a sled and a rifle mounted in their shoulder. If your not zeroing your scope to correct for the errors you introduce into the POA, you will not be ready to make very accurate shots in a hunting scenario.
All I'm pointing out is, like in that the video, a sled gives guys a false confidence in their shooting ability.
And yes, I can make a fairly accurate pie plate shot off hand out to 100yds..
