I've never used one but one problem I could see is that you're going to have a different stock weld and eye relief because the Lead Sled holds your buttstock in an enclosed shroud. Therefore the rear of the stock isn't all the way in your shoulder. But it probably won't change that much from the LS to your real world point of aim. I bought a Caldwell Steady Rest NXT for the reason I mentioned above. It's nice and steady and I can still shoulder the rifle. But I do understand your reasons for getting the LS.
