[QUOTE="Mikecr, post: 921825, member: 1521"] ADD: Some of this is of course dependent on case design and load density also. If you want PROOF of density over powder or brass weight try this experiment: Chamber a round with the barrel pointed up and slowly lower to a rest. Note the velocity on firing. Now chamber a round with the barrel pointed down, and slowly raise to a rest. Note the velocity on firing. The lower your fill, the greater the difference, regardless of same powder and brass weight. You'll see the same from cases weighing the same, and charged the same, but of different H20 capacity(affecting load density). [/QUOTE]
