As a total newbie in forming one caliber from another, some time back I decided to see what would happen if I tried to form some .350 Rem Mag cases from some 7mm Rem Mag brass simply by using the 350 Mag sizer. I ended up with some wrinkles in the shoulder/neck due to the moving of a LOT of brass. Would annealing previous to the resizing process alleviate this, or is there another step required? It seems like it should be a relatively simple procedure since both calibers use the same parent brass.
