I shoot mainly small fixed scopes anyway as their lighter and never need twiddling while out pesting as I need to point n shoot and instinctively know my holds, the two variable scopes I do have are set and taped up so they can’t move, one being my ratter(1-5-28) set on 1.5 and the other my hft scope(3-12-34) set on 7

I would not think of changing mag or focus while out shooting
