The manufacturer does have a BIT of data online:
http://www.dlswc.co.za/Reload/default.asp There are aa few loads listed for the .44 Remington under Handgun Data.
A comparative burn rate chart shows that this powder is similar in burn rate to H-110/W296, and the loads shown on the web page above are very similar to the ones for a .44 using these two powders given the bullet weights shown. That's by no means a suggestion to use H-110/W296 loads with this particular powder, because, the similarities may end there.
