[QUOTE="Steve Sheasly, post: 1508983, member: 103826"] The point is that even with the same lot -- same brand --- cutting the exact same size and shape cup out other the same sheet of brass can and sometimes will result in different weights. Lets take this example. Lets take 2 cases identical - lets drop one at a time into a glass of water and measure the displaced water. Lets say that the displaced water is exactly the same in grains of weight. Ok -- now lets weigh the brass cartridges --- they do not weight the same because of different densities in the parent brass. I have found this to be the case by my own measurements. Up to 5 grains off. Will this make a difference to every one? Nope not by a long shot (pun intended) but to me it does. So volume is the only way for ME to sort brass and the only way at all to get the same void volume with the powder in the case ready to seat the bullet. Wich by the way is super critical to void volume. If you do not seat the bullet with the same depth of the projectile then measuring volume is worthless. In my opinion we with brass not because it makes our guns lighter (joke) but because we want the same exact void volume so the powder during ignition burns the exact or as close to the exact same as possible.
