I have three powder measures and not one of them will throw identical charges to the others. Also run the same test using one measure and see the difference you get from throw to throw. Are you a tapper, are you a level person? The best measure Ifound is a Thompson Center funnel type clear see through measure.

There was a discussion a while back. The question was, is it worth while to weigh your charge (according to volume of course). Many people felt it a waste of time and that a simple powder measure produced better results. I personally tested that theory of weighted charges VS measured charges. I shot from 100 yards so the possibility of a wider group would be more likely. The weighed charges in three different tests out shot the measured for group size. Not by much, but they did produce a tighter group.

I think that's why many people claim such excellent accuracy with pellets. They basically have a measured load (although my understanding is, pellets vary a great deal. Perhaps someone can comment on this point). which stayed the same shot to shot.

And interesting test doegirl. Does this mean you're going to start measuring loads for you range and hunting trips?
