Being in a fully supported revolver chamber, the only difference in brass that matters is length. Length of the brass is the only difference between the two, as thickness bears no relevance as it is a revolver round. Some have essentially loaded 357 rounds in 38 brass by seating the bullet WAY out, essentially creating the same powder capacity as 357. There was a particular Lee cast no!d that was popular for this as it had two lube groves and the higher one can be used as a crimp groove to put you very near 357 OAL. I'm not recommending this as there are some liability issues. For example, your children get hold of some of your reloads after you kick it and shoot the 357/38 (because the headstamp is 38) out of a 38... Being unsafe.

Yes you can load download 357 to where its essentially a hot 38. I have a very good 158 wadcutter load in 357 that mirrors a 38 158 LRN in velocity, but is stupid accurate.
