.308hunter,
Like everyone else has said, you CAN weigh out your charges like that........but theremay not bemuch to be gained by it.

But if you do try it, you need to get the exact weight established for every powder and cut (2fg, 3fg) you load. To do this, measure out and weigh at least 10 loads at whatever volume you want to reproduce, average those weights and the average is your target weight - doing it this way should make your load more consistent.

I did this a couple years back and I really didn't like the results, as I got better groups using the old hand measure at the range than with the pre-weighed charges. But I tried that only with 2fg Clean Shot powder which had huge granuals - so that could have made a difference. One day I'm gonna try weighing again with 777 powder, I think thatmight work better.

Good Luck if you try it
