I tumble in corn cob media with whatever brand case polish I have at the time. Do it while I am busy doing something else or just relaxing. I don't sit and wait for it to be done.

Then I do all prep work, then load. That is all I did for years.

Lately, I have been doing all prep work, then put in tumbler with Nufinish car polish and walnut media. It gives it a great shine in not very much time, and cleans the necks much better. Then prime and load.

All my older handloads look much "dirtier"in comparison to later ones. Is a great shine needed? No. But it really doesn't require much more work/time to get it.......
