To the OP's question......Between the two rests mentioned, I would choose the bulls bag......I would never use a Lead Sled.....it is just a poor concept for all the reasons noted......particularly the point of impact (POI) being no where near the same when one is shooting off-hand. That being said, sighting in with the bulls bag will also net a different POI from shooting off-hand, just not as much. The bulls bag website inadvertently admits this fact by it's claims that the bag minimizes muzzle jump (remember the bullet is still in the barrel at early stages of recoil), yet elsewhere on the site they claim that the bulls bag does not negatively affect your POI.
From the video's on the web site, it clearly shows the shooter steering the rifle with his upper body for windage adjustment, and lifting the buttstock out of the "cradle" for elevation.
Using the good old fashioned 2-bag (sand bags) system with a quality adjustable tri-pod which allows for minute directional changes, one can develop a form that greatly minimizes body contact which CAN cause variations in POI. I say "can" because an astute shooter who maintains consistent shooting form can greatly minimize POI changes caused by the rest platform.
The site is loaded with hype and more than generous customer target measurements. Apparently the Lead Sled is their biggest competitor.
I have no problem with this companies 2- bag designs.
