I know of vary FEW shooters who begin setting up a rifle free hand, all use at least some kind of support to stabalize the rifle be it a tree limb 4x4 limber, sand bags, or rifle rest, and the leadsled is just a upgrade to the rifle rest does all that the others do but also has the ability to ruduce the felt recoil, and yes they help to set a rifle up as there is minimal movement when you fire.
