That is a sweet sled and appears to allow for some muzzle rise and recoil. I seldom weight down my sled unless im shooting top end loads or if its going to be a long range day.

I agree though. I get the groups i want on a sled first then the final sight in is off of a rest. POI may or may not change depending on the weight of the sled and recoil. Even your own body mass has an effect.

Ive got some low kickers that hit close enough they dont need final adjustments.
