This. I like my brass clean and in good structural condition. Some don't care. meh.For me the purpose of cleaning the cases & primer pockets is to achieve a consistent load. Whether it's a good seating of the primer, bullet, or even a consistent powder charge....that is why I do it. Plus you get to inspect the cases for possible wear or even cracks.
Others will say just deprime, reload, & repeat until the case splits.....probably not the best advice or a best practice, but to each their own.
Those are good reasons to me guys. Have you ever tested them both ways to see if there was a practical performance difference?
I'm gathering that your talking about the reloading consistency?
It is a waste of time unless you are shooting competition. The decapping pin cleans the flash hole. That is all that is necessary. IMO
