Also, the Lead Sled IS a neat tool. BUT I have seen to many scopes turned to junk when fired from fixed rests that don't allow a moderate bit of movement or recoil absorption when fired. The energy has to go somewhere, the weakest link is typically the crosshairs/turret assembly of a scope. Just be careful here.
Wouldn't this be exactly opposite? IF the gun is not moving under recoil then the scope is not moving under recoil so how could the scope get damaged just sitting there?
