Re: New brass prep?
Depends upon what kind of brass. If it is Nosler or Norma brass then just load it and shoot. The primer holes are drilled so you don't have to deburr them and the necks are inside and outside chamferred.
If it is WW or Remington then you will probably have to run it through a neck sizer or full length sizer to get the dents out of the neck. Then you could deburr the flash holes and chamfer.
I don't know about Lapua, they never sell it in any caliber I reload for.
