I have draw dies from RCE, I tried Brass2Bullets, and I have Lee dies on order. I believe B2B dies are probably Lee dies. You can get Lee bullet standard sizing dies for 30 dollars each, or 38 dollars for a custom size. I have a few on order, and will let you know when they come. It looks like 4 steps between 9mm and 30 cal is best. The steps between sizing get smaller as the diameter gets smaller because there is a sizable chunk of solid brass building up in the case head area. If you use 38 special, you will have to get a rim shear die from David Corbin or RCE to get rid of the rim before you start to resize. I am using 57 brass to make 180 gr bullets, I do not know how much heavier you want to go. I think 57 brass will make a heavier 30 cal bullet than 9mm although I am not sure since I have not successfully gone from 9mm to 30 cal yet. (I am just judging from pics I have seen posted here.) I think you would need to trim quite a bit off a 38 special case as it would make an extremely long case if de-rimmed and reduced to 30 cal, but I am just guessing since I have never done it.
Look at pics on this thread for what is possible from 9mm brass. (thanks BTS)
