N32C load for 9mm?

So, I know this isn't ideal, but I want to load up some 9mm and was able to get some Berry's preferred plated 115gn RN bullets and some N32C power.

Is the closest official load data for a 380 100gn buttet. I've seen random person indicate they were going to try this with 3-3.5gn powder on 115g.
I can't find anybody posting a load for this combo.
Anybody know where I can find a potential safe starting load on this combo?

Downloaded Gordons Reloading Tool and put in Hornady XTP 115g and N32C, it indicates safe pressure for these up to 4.6g. Beyond that it says pressed load and warning pressures. But, I've read that Berry's plated bullets (wasn't in the database) can cause increase friction over lead/jacketed bullets .
Looks like I may try to start at 3.0g and work up.
