denton's explanation is a great example of getting too wrapped up in theory to see the reality. He claims that "for practically all applications" weighing charges doesn't matter, while attempting to prove it with a very limited set of information. NOPE. Sure, there are some examples where that is true, but that does not make it universally true, or even most of the time.
It's easy to find plenty of examples where weighing charges does show a significant difference on target. Take a 223 & Varget load that has an accuracy node about 0.3gr wide, which is fairly common. Now load that with a powder measure that varies +/- 0.4gr with Varget (meaning dropped charges span a range of 0.8gr), which is also fairly common. If you don't weigh those charges, you get a fair number that are way outside the accuracy node and the difference can be significant when shooting at extended ranges on small targets like ground squirrels. Good for denton if his powder measure is more consistent than that, but there's a big gap between saying it works for that one powder measure, and saying "practically all applications".
As to the weighing vs measuring argument - powder energy is a function of the mass of the powder, not the volume dispensed, and most powder measures dispense by volume. Dispensing without weighing can sometimes be as accurate, but weighing is never less accurate. If someone claims it is, their test was flawed or the sample size was too small.
Same goes for weighing cases. For example I've got a 357 Sig load, and a batch of brass with weights in two distinct groups. Velocity from the heavier group of brass is approximately 100 fps faster than the lighter group (about 1750 fps vs 1650 fps). That makes a noticeable difference, so I choose to sort that brass.
Often this stuff doesn't matter, but sometimes it does.
