Shaking each round would take a lot of time. But maybe you could roll
the cartridges down a incline. The powder tumbling inside would take
some energy. A cartridge without powder might fall a bit further out
and one with a double load might fall short.

But would it work well enough? Tom said he had one short every 5,000 rounds or
so.


Would probably only work for rimless brass, if it works at all. But
could be worth trying.

I think that the powder weight is a small fraction of the weight of the entire
round.
