I wish I could get an email or PM to an Administrator on 1911forum.com to ask permission to repost his entire post, but I can't find a way to do it. Therefore, I copied part of Gerk's post below along with a link to the thread. Gerk's post is #13 in the thread. Everyone who reloads or is considering doing so should read it, even though you may have no interest in 9X23. His warning/advice spans the entire reloading spectrum. (Oh yes, I have shot 9X23 in my 38 Super, but never again.)

I am always amazed when such sound advice is freely given and not taken.
While some do use their 38 Super barrels to shoot the 9x23 out of, when considering the stark differences in operating pressure, case and chamber specifications reconsideration should move to the top of the list to the prudent Handloader.
You don’t have to be an old Handloader to be wise.
(There is no rule against this, but some act as if there were)
This is more of a “should I” than a “can I” decision to make.
