+1 they don't look like you need to worry about (but if they do blow 1/2 your face off I didn't say shit) they'll be fine.
What had me wondering, since they are not smooth and shiny anymore, is when I was sizing them they tended to stick in the die even with a good amount of lube.
Try some lube on a Q-tip inside the necks to see if this helps.Clean brass always hangs on my expander more than dirty so I'll lube inside the neck one in ten as I'm sizing clean brass.
I don't want any wet lube inside the case.
I assumed everyone cleaned their brass after sizing and you know what happens when I assume. FJ's right about the wet lube if you don't clean after you size is bad Ju-Ju with powder.
