Not HP's, but I have loaded many Ranier 115 Gr RN bullets. Start at the bottom of jacketed data and work up. They are not limited to lead data, but can not use some max jacketed data either. Plated bullets are their own little animal.
That said, I routinely shoot the 115 Ranier at max jacketed data with N330, WSF, and AA #5. I would suggest stopping at 80% of jacketed data if you are not comfortable with it.
