I am just getting set up for the 358 Hooiser, I got a barrel ordered, dies will be ordered this week. One of the tips I have heard is to trim your brass first to 1.8, then size, then check and retrim to 1.8. Heard that a full lenght 358 winchester brass won't go all the way in the die unless it is trimmed first. Also there is a guy in Bloomfield ,IN AJ Brown who sells sized brass and loaded ammo. He is who I ordered my barrel from.
