Redding makes (or used to) a ring set for 38/357 and 44 Spec/44 mag. I use them quite often.I have heard that 38 dies come with a spacer ring to change the height. I have never seen such a spacer, but I have seen references to it. It would be a handy way to allow the lock ring to remain the same. It would be about 1/10" of an inch thick.

For my 357 I found out backing the dies out about 2 full turns from the 38 setting works just dandy. May not work for you but worth a try.
