I have been using a lead sled for about a month now on and off as one of my range buddys has one. For hard kicking rifles and slug guns it is really nice. One thing I noticed so far and it may not be typical of your results is this, this rest is tough on scopes. A good scope mounted well seems to be ok, but a cheaper model that might be suspect anyway just lasts no time at all on the sled. Now this may not be a truly accurate statement as my experience with this is limited at this time, and maybe the scope would have blown anyways. But the gun does recoil differently in the sled and it seems to me more of the energy is being transmitted to the scope than is by shooting from a more traditional type of rest where the shooter takes the recoil in the shoulder. Due to the fact that my experience is limited with this, I was wondering if this what others were seeing or not.
