You're in the same boat as me. I'm building a 7saum hunting rifle. No luck finding brass but was able to find nosler accubond 160 grain ammo at powder valley so I ordered 4 boxes. Not the cheapest route but I'll have some break in ammo and 80 pieces of brass out of the deal. And since the 162 amax production has been suspended I'm leaning toward these accubonds anyway.
