I've heard that the Lead-Sled causes scopes, mounts, rings, and stocks to break. Especially on the big magnums. All the recoil energy has to be transfered somewhere, so it goesright into the gun. I wouldn't use one on my magnums, small calibers yes, but they don't recoil enough to need a lead-sled. If you can't handle the recoil, either get a smaller gun, muzzle break, recoil pad, shoulder pad, etc... IMO
