Those who never shoot off the bench apparently only shot factory ammo....no load development needed. Bench shooting (shooting off the bench not at it) is necessary for accuracy while developing loads. It's also a way to get the sight-in close. I have found that that rifles need to be checked and sometimes adjusted for zero from field positions after the bench sight-in, point of impact is often a little different from bench to off-hand.
I saw my dad miss a fine buck because he rested his Mod 70 directly on a fence post. See John's comments above about resting on hard surfaces.
