Been testing the same tune principles in my TX 200 over the past few months. It’s a simple test, pick up the gun and fire at 55 yards and see if it’s level. So far from 15-25 degrees it’s not shifted a click since February, not a single click at 55 yards.

I’ve got nick’s tune in another gun and that’s going though testing as well. Early days but the sight picture is as others have said.
