Brass today is rolled to thickness with much less stress. The stress today in ammo comes from firing guns, with or without Brasso. With all the handling it takes to make and use reloads not much ammonia would be left and reloads don’t have a long life expectance anyway. I am not saying any one should use Brasso. The hardening and cracking in reloads will happen with use. And all the people said “Who cares?”

I agree. The paranoia about Brasso is out of proportion. Actually the current ammonia in Brasso is only 2-3% by weight. A small amount dispersed in a tumbler of dry media would be negligible.
The majority of it is mineral spirits ( Stoddard)
No I would not leave brass soaking in ammonia but the tiny amount in a tumbler I doubt would do anything.
