I bought 100 pieces of Privi .338 Lapua brass at The Stockade in Westminister, California. Not the highest quality but good for practice. .338 Lapua usually goes for about $6.00/rd loaded. I can do it for about $3.00/rd loading my own. I use a 300gr SMK bullet over 93gr of Retumbo and a Large Magnum Rifle primer. I am zeroed in at 600 yards.
