New 7mm Dakota brass prep?

I just recieved my new 7mm dakota brass from dakota, It is made by Norma, what prep should I do to it so it can be ready for loading? I have a sinclair tool for deburring and chamfering the inside of the flashhole, is this good to do?
I also noticed that this tool makes the flashole slightly bigger will this create a problem of pressure?

I do an extremely light clean-up with K&M outside neck turning tool--Usually only touches some of the neck mouth and the neck should juncture.

Norma flash holes are drilled and require no preparation. For hunting rounds, straightening and chamfering should do it.
