never tried anything else except c. cob.
i've had this w. hull a long time and
it will probably be enough to last me
until i'm too old and feeble to load.
it gets a squirt of polish when it starts
to get tired and tossed when too dirty to use.
i would think that any type of nut hull or
quantity of similar small particles would do
the job of cleaning with a dash of polish.
i see the thing now is these stainless
steel "needles" that dash around and
knock grime and mung off the cases.
when i run out of my stash, maybe they'll
have something that is effortless and
really inexpensive.
(inexpensive- that's a joke ! !)
