I used mine for the first time to night seating 50 bullets and the gauge kinda puzzed me,with readings at .030,.040,.045.,.050 with it set at .000 .Does anyone know what the tolerance should be and what I can do beside annealing cases to get this more on track.Also I was wondeing what kinda of group at 100 yards and 500 yards do you think you will get shooting bullets seated at .030 mixed with ones seated at .050 . Thanks for all your help!
