I would suggest setting it for your most used load--which might actually be a total of one, in some cases, and then NOT moving it for additional loads, but simply remember where they strike. Reason...the adjusting screw can get a bit loose and too easy to move. Had a Sauer sidelock which had a screw that turned too easily and once in a while, the shot would be off. Inspection showed that the screw had been turned somehow or another. I guess you could also put some locking compound on the screw to keep it from moving. Good luck! Steve
