NP, I didnt take it as a flame and the "beating up on Sludge" comment was tounge in cheek. I wasnt clear about my concern. I really dont care if a scale is off a whole tenth of a grain or not. Just so long as it has uniform results. Now, I would like to have the scale accurate, but if I were on a deserted island and was given the choice between one that was right, but had a high SD or one that perhaps was a tenth off or so but kept the SD low... I would choose the low SD one. Now, were I to be switching scales for some reason then being calibrated differently would definately be a hinderance.
I plan on experimenting a bit more since I have the analytical scale here. One, to see if the previous results hold for a coarse extruded powder and I also think I will let the powdermaster throw the charges low, and then using the powdermaster, trickle up carefully until it trips over to the right weight. Take those to the analytical scale and see if the SD tightenes up any using that method. Just curiosities on my part. I have also thought about doing some primer testing using the analytical balance to see how much corrilation there is between weight and MV given identical loads from the same rifle. Ive read other articles on it, but not all of my questions were answered.
Hell, that Sartorius scale is a bit old. It may never go to work again for anything else other than my little anal retentive experimentation LOL
It has dispelled one myth of mine reguarding the SD of loads from the beam vs those from the digital scale. It may yet educate me further.
