Or you can go 1 or 2 other ways. First you can get another bullet seating die and set it up for the 38s. (the flaring die is a cinch to adjust between the two) or you can simply set your dies up for the 38s and get a .135 spacer from Midwayusa.com so you can load 357s without adjusting the dies. I personally have 2 set of dies.
