i know you didn't ask, but a good recipe i found for 30/06 is 48 grns imr 4064 and 165 gr projectile has worked good for three different rifles. also x2 on tumble first.
YES!!! like I said earlier, if you size dirty brass the dirt ends up in the die and leads to stuck cases. you can and some people do tumble them again after, but imo it's not needed and is just doing twice the work.

how dirty can rifle brass get when fired in a bolt gun? tumble brass? i have loaded for many years and don't own a tumbler. for sizing bottle neck cases i use a dry mica powder on the inside of the neck and very little wet lube on the outside of the case. when loading for max accuracy neck size only for same rifle clean flash out of primer pocket make sure flash hole is uniform trim all to same length. then weigh and measure all cases then seperate into small lots then chamfer case mouth and load. used this method for all loading and have good accuray 1 moa in a good rifle and minit of deer in others
a lot of it is oxidation and/or mold if stored in an un airconditioned area. I've seen some so bad they couldn't chamber. and they are almost sticky and then collect the burnt powder after shot. if they are a tight fitting neck sized round you really want them clean and lubed. for a revolver it doesn't matter as much. it really won't effect how they shoot as long as they chamber. bright and shiny are just more visually pleasing to me.
