I use necked-up Winchester 308 brass. Lapua is nice stuff, but overkill for hunting ammo. It is a grunt to neck up as the Lapua brass is very tough.
If you are unsure how to expand it, go to sinclair international's website and look for a .338 expander mandrel die (Likely in with the neck turning equipment) . They are dirt cheap and dead simple to use. Use some case lube of the mandrel and fly at it.
If you like, send your barss to me and I will neck it up for you.
