About that .338Fed. on this continent, I've always considered brass for the .243Win., .260Rem., 7mm/08, .308Win., .338 Fed. and .358 Win. to be VERY plentiful - not only cheap to buy, but mostly free as range pickup, especially after the local ERT (Emergency Response Team) has their qualifications.

I can see your point if the ammo does not accompany you to where you are hunting.
