Loaded up some 7.62x39 now this is OLDDDDD...... small primed brass not to beat up cleaned (tumbled) loaded and stored going shooting and got a few hundred out and all spoted up R.P. brass will this keep getting worse?

Pics would help.
Will it keep getting worse? probably. depends on what's causing the spots.

Can you stop it? again, depends on what's causing the spots.

Most likely the brass is just tarnishing and if that's the case it's no big deal.

Once I left some brass in the tumbler with the polishing media for a period of time. I was in a hurry, shut the tumbler off, then forgot to process the brass for a couple weeks.

The brass had some spots on it, probably from the polishing compound used on the media.

The brass shot fine.

Now, I, at least, dump out the tumbler and separate the polishing media from the brass if I can't completely process the brass when I shut the tumbler off.

May not be your problem.
