I was fortunate to obtain some factory loaded ($15 a box)Federal STW ammo (shot 3/4" at 100 & 2 1/2" at 200, I use it for foulers)for what it would have cost to purchase and load the WW for. I use WW for the most part. The Federal I have I use after I have some development done with the WW to give me good starting points. The Federal is really nice brass. That said there really is nothing wrong with the WW. The primer pockets do loosen a lot easier on the WW than the Federal though. If you know of a place to get Federal 8Mag brass, which is the parent case of the STW, let us know Iíll take 1000 right away.
