So I was loading a batch of 30-06 this afternoon and decided to load half this batch by weight and the other half by volume.
My brass is all from the same lot so they are all pretty darn close as far as having the same internal volume. I used my Lee perfect powder measure to dispense 34.22cc of IMR 4895 or 47 grains approximately.
I weighed each charge and they did vary not much about .02 grains again in weight. It was my understanding that even though the weight may change the volume should stay the same.
I have seen several posts of people throwing charges that vary , from powder measures, but that should happen but the volume should stay the same correct?
Lee has IMR 4895 VMD at .728. I always wondered how accurate this number is.
Im very interested to compare these when I shoot them.
The whole idea behind this was twofold 1 every electronic scale I have drifts, 2nd save time. The hoppers can dispense powders alot faster than any of my electronic dispensing machines
