I did not realize the site picture could change. Guess a person could hold it right. Also one thing with a muzzy is it would need to be lifted like a pump would.
Though I have never heard of a issue with the lead sled and it cracking stocks. Main thing was to take the human part out of it when sighting and the recoil on my bad shoulder. Though I will make sure to fire it like I do in the woods. Last year a buddy asked why I was sitting on a 5 gallon bucket seat and the tripod I have for it and not the nice shooting bench. My answer was that bench is not in the woods with me, this bucket and tripod is however.
