I'm changing over to Lapua brass for my .308's,heard great things about it.Is there anything other than chamfering the mouths and running the sizer ball through the necks that I need to do?Thanks for any advice.
Not really, that about covers it. Depending on what brass you’re coming from, you might want to back the charge off slightly and re-establish your target velocity.
For the 6BR brass, I don't do anything with it before loading it. I will measure a few to make sure they're like the last batch, but they always have been.
