Basically the Lapua brass should be ready to run straight out of the box. I would run it all through a full length die for the first loading only, just to make sure the necks are still straight from shipping, then never again, unless it's shared in multiple guns ( I use a seperate body die when bolt closing gets too stiff). Sometimes you may have to "bump" the shoulders also. Most of the other brass "chores" are not required for Lapua brass ( flash hole deburring, pocket uniforming, casemouth chamfering, etc.). That's one of the good things about Lapua brass, it's one of those times you really do get what you've paid for.
