Loosening turret on Zero takes seconds and locks up tight.Mainly a T7 and a Rock Chucker collecting dust. Thought about switching to the Zero but that requires adjusting dies which not a big deal but when you have them dialed in. Also after watching several YouTube videos I don't like that the turret needs to be loosened to rotate between dies. I get the precision aspect and open to change if I had the ability to use but as of now I'm sticking with what I got.
