I'm replacing a 6.5 Creedmoor barrel with a 6mm Creedmoor barrel. I understand you can use the same 6.5mm sizing die. I use a Redding bushing die now. Planning to use Lapua 6mm Ceedmoor brass. What size neck bushings are you using with Lapua brass? I did just pick up a bunch of once fired brass and it measures .016 neck thickness.
. I will also be using a LE Wilson .242 mandrel as a final step.

I use either a .268" or .266" (depending on how much neck tension I want) followed by a .241" mandrel, both work great. If I wasn't using a mandrel step, then .268"-.270" would probably be it.
