Hodgdon powder is marketed using
some of the same numbers as the IMR series powder by Dupont. You should be aware that the loading data for the
products of these two companies is not the same. Any of the Hodgdon powders that have 4 digits are made with
an improved technology that makes their powder far less temperature sensitive than any powder made by other manufacturers.
Hodgdon makes another great powder called Varget that also uses this patented technology. Hodgdon calls this
series their "Extreme" powders.
Temperature sensitivity makes a huge difference to long range shooters. We sight in our rifles in
Florida and hunt in Pennsylvania during the winter. There is quite a temperature difference. Of course, we always
verify our sight settings when we get there, but the velociy is much slower in cold weather. This change in velocity has a
bad effect on long range trajectory. This is no longer a problem when using any of the Hodgdon Extreme powders and the
consistant accuracy that we get is as good as any other powder that I've ever tried.
