Not aware of specific resource for this brand. I would use jacket data over cast data if I were to load plated bullets such as these.
What is not working well? Are you testing the rounds over a chronograph trying to get a desired velocity or are you having feeding issues?
As long as your not pushing them above about 1300fps your good. I load most played at jacketed specs for380, 38spl, 9mm and 45acp, all max out at about 1150fps. I typically load about .2-.3grains less than max jacked data from the lee or lyman book. For magnums, 40, 10mm etc I tend to make sure im just not going much over 1250-1300fps, usually low-mid range load data.
