My one book one caliber manual contains published information on a Winchester 124 grain LRN with WSF. Indicates min load of 4.0 grains and max load of 4.7 grains. You certainly can use this as a starting point for your lighter 115 grain LRN's, even starting at 4.2 grains min.
The same book has WSF data for Sierra 115 RN FMJ's that shows min load of 4.8 gr to max load of 5.5gr. I've found that the minimum Sierra FMJ loads work well for lead or plated applications.
Hodgdon also has published data available online for WSF, start at or below the start load for 115gr RN-FMJ and you should be OK for lead.
Start low and work up is the best advice I can provide, the above is published information to get started. So far as COL is concerned, load some dummy rounds and make sure they work in your magazine and pass the barrel plunk test. With nose differences between jacketed and lead RN's, you may not be able to use the same COL for both.

Welcome to THR.
+1 to what john16443 posted. 1999 Winchester load data has 124 gr RN lead load data for WSF. You could always use load data for a slightly heavier bullet so perhaps you can reference the powder charges for 124 gr lead bullet to conduct your powder work up for the 115 gr lead RN bullet (maybe go up to 5.0 gr)?
FWIW, I use WSF for full-power jacketed 9mm bullet loads but use W231/HP-38 for lead target loads.

According to the Hodgdon load data: http://www.hodgdon.com/
124 GR. LEAD RN Winchester WSF .355" 1.169" 4.0 945 22,200 PSI 4.7 1055 27,300 PSI
For some unknown reason, they don't list a WSF/115 LRN combination. Maybe then know something. However, extrapolating from loads with heavier bullets is not likely to be dangerous.
WSF, in my experience, is a tame and predictable powder. Start at 4.2 or 4.3gr. and work up from there until it cycles the slide reliably and convincingly. The worst that will happen with the starting load is that there won't be enough energy to cycle the slide and it won't burn very clean.
