Actually, there's a variable here that wasn't considered in the original question: Do you have to lube your cases to resize them?? With straight walled cases like 10mm, 9mm, or 45 ACP you can resize with carbide dies no problem. With .357 Sig or 50 AE you have to lube the cases. (Note: I have a carbide 357 Sig die, but the box clearly says that you have to lube the cases anyway) There is no carbide 50 AE die available.
With carbide dies, you can tumble first and then resize and deprime, PROVIDING that you get all the red dust from the walnut shells off the cases. If you don't, then the cases get dirty again when the size die smears the red dust all over the case. With cases you have to lube, I used to size and deprime first, wash all the case lube off and dry the cases, and then tumble them. I am getting away from that because of having to pick the #@%$#*^%*&%$^#&*^% walnut shells out of the primer holes. As such, I tumble with dryer sheets in the walnut media, which keeps the red dust problem at bay, and recently it seems to actually make the shells get cleaner faster. (Really!!) Then I either resize and reload, or lube, resize, wash and dry, and then reload. I have a cookie sheet full of resized 357 Sig brass in the oven at 225 F. as I am writing this. (And NO, it takes a lot more heat than that to change the temper on a case!! My 50AE cases come out of my Desert Eagle at about 300 F. and they're fine.)
