been thinking about acuracy.

I know you say that a .5gr difference in powder charges doesn't matter but I have to disagree with you. My testing shows that a .5gr difference does make a big difference in group size at times. I have seen quite a few times when the .5gr change in the charge has made 1/2" or more in group size. It may not affect velocity and pressure that much but it must affect the barrel harmonics.
