Well, the idea that one must have shiny, super-clean brass must have originated with the manufacturers/marketers of Cleaning equipment.
For 2½ decades, I loaded all my ammo without any tumbler/other cleaning device. It all worked fine, and I am still using the 30-06 dies
I originally purchased in 1964, so I did not do my dies any harm, obviously.
But, I always wiped my brass carefully before lubing/sizing.
Range brass with some exterior tarnish was treated with steel wool. [Fine, then extra fine].
Cleaning primer pockets is largely a waste of time, unless you are shooting long range targets or bench rest.
If you must clean them each firing...go for it!! Myself, for hunting ammo, I tumble every 4/5th firing.
BTW, I do have two Vibratory tumblers, and I will occasionally clean my brass, either with Walnut or treated Corncob.
But I have better things to do with my time than clean every firing.
One little thing I do, though, is immediately after firing a round at the range, I take some steel wool and wipe the
carbon off the outside of the neck. This stuff becomes increasingly difficult to remove the longer you leave it on.
Whatever you decide though, is
entirely up to you. I do not believe that being anal about cleaning is bad, just a bit of overkill, possibly.
