What is considered a mild load for a 38 special? I have always shot WWB 38 special RN FMJ. It that ok?

I think I will buy one box of 38 LC to have just for the heck of it but shoot the 38 special for plinking. It would be cool to get a period correct box of ammo. Probably to hard to find and out of my price range though.

Thanks a ton guys you have been a wealth of knowledge and help. A special thanks to mikepriwer you are the man.
