No, you can't stop a muzzle, Dusty. You might be saying that tongue in cheek or not. I thought the only person that still believes in a stopped muzzle was Calfee. Lol!Youd be surprised at how much even a humidity change throws it off. You can tune a barrel with a tuner to its smallest movement, go have a sammich and try again and its like you never touched it. You can “stop” a muzzle but it wont stay. Itll go wild before it even shows you on the target its going out of tune
