No experience yet but I would expect that if the gun is not allowed to let the barrel rise normally as it would when held there could be a difference. I would make sure that the barrel was not held down and the recoil portion of the sled does not control how the gun rises in recoil. I have a similar rest that uses weight in the base but the recoil restriction is a strap that allows the rifle to move in recoil. I think the Lead Sled has a solid plate that the butt rests against which might be different.
