If I'm starting with a new batch of brass I seperate them by manufacturer. Then I resize and trim every one of them. After that I seperate the "same manufacture" brass by weight.
when I'm loading for my "groundhog gun" I really get picky. For this gun, I weigh every single powder charge. I also have a tweezers... I add/remove a single pellet of powder until I reach the correct weight... ok... maybe I get a little fanatical with this load!!
