POWDER BURN TABLE from Hodgdon/IMR – LoadData.com with 197 powders
LoadData.com has its own burn rate chart. It is more detailed than the official Hodgdon/IMR charts. We recommend that you start with the Hodgdon/IMR lists. However, if you are unable to find a powder on the Hodgdon/IMR charts above, then you can consult the LoadData.com alternative which lists 197 powders. Also, we recommend that you start cautiously with any powder. We suggest starting at the lowest end of the official load recommendations. Even within the same burn range, a ball powder may behave differently to an extruded powder. Some powders are more sensitive to temperature than others. Among all the powders available, the Alliant TS (temp stabilized) series and the popular Hodgdon powders such as H4350 made by ADI Australia are the best.
