Using Lapua brass you need to check your fired neck diameter. My Winchester brass fired is.340 and loaded Lapua brass measures .3375. I don’t think that is enough neck clearance and could also show pressure issues. I measured some Lapua brass with a tube mic and it runs right at .015”. .015 + .015 + .308 = .338 and with fired brass measuring .340. Just a heads up about this. I’ve got some loaded that Im going to break down and turn the necks to take about .001 off of each side.
