Note you can convert it to grains and FPS on the right hand task bar.

I am trying to match their data to the Alliant Nitrochemie powders R 17, 26, 33 and 50. So far can't tell which if any are an exact match. Their burn rate chart is pretty general as it should be. Here is the comparative burn rate: http://www.reload-swiss.com/en/reload_swiss/service_3/relative_abbrenngeschwindigkeit_2/index.php

Still doesn't tell me if there is a match for Reloder 26. Interesting anyway.
