I have mixed opinions on the need to resize full length brass hulls if they are to be used in one gun only and both chambers match.

When I shot several different 16's I did have a need to resize the RMC brass hulls, because the chambers varied. Now that I only shoot one 16 I have not resized them in 20 plus firings. They are simply fire-formed to the chamber. I do clean them in a hydro-sonic bath and occasionally shine them, but the is the extent of haul care.
