I had a message from a concerned poster about my remark in another thread. I had said I got tired of resetting the dies form .38 to .357 and bought another set. He wanted to know what the problem was. Just wanted to say in case some others thought the same thing, NO PROBLEM. .357 cases are the same diam. as .38 so the same dies for both, just have to adjust for the differnt case length between the two. It states this by Lee: Note: you may use the 38 Special die set to reload for the 357 Mag. You would have to back out the Powder Thru Expander Die, and the Bullet Seating and Crimping Die about 2 turns to compensate for the longer 357 case.
