Here's a thread about developing a load from an unknown powder:

In your case, you have a big leg up as it's a "known" powder, there just aren't any published loads with it for your application (9.3X62).
Firstly, just because there aren't any published loads for your application, doesn't mean that using that powder is "dangerous". At worst it's not optimal, e.g. as an extreme example, using US869 in the 9mm Luger. In many cases, it might work well, but commercial load development is time consuming and costly and few handloaderss load for 9.3X62.
In this case you have published loads and a Burn Rate Chart. You need "reference loads" with powders that are near Superformance in Burn Rate and have published loads for the 9.3X62. Importantly you need a chronograph as well. The chronograph is a very good estimator of pressure.
