Loading .38 special

[Cyberbeer]

I was hoping to find some data on loading .38 special using HP-38 powder. I've been loading .45 for the past few months and my wife just picked up a LCR for CCW. So now its on to .38 so she can shoot it as much as she wants.

If I understand correctly .38 is a low pressure round like the .45 and the brass can be used multiple times. I'm also assuming that because its a straight walled, low pressure case it shouldnt need trimming between reloads.
