I am just wondering about plinking ammo for 223 mostly. How many people don't bother chamfering and deburrig after trimming and throw the brass in a tumbler for a while to deburr? I have read about some people doing this but can't find a lot of info on it. I trim using a possum hollow trimmer in a power drill and think it would be easier to tumble after, I'm not loading for supreme accuracy.
