AR2209 (aka H4350) is a good powder with a useful burning rate for a range of cartridges I load for (243, 250 Sav, 257 Roberts x 3, 6.5x55, 7x57, 280, 30-06). We don't have the huge range of powders you guys get. We get the locally made ADI stuff (sold in the U.S. as Hodgdon Extreme) and a bit of Winchester and Reloder powders every couple of years. Reloder 19 is another good burning rate but can be a bit iffy to get at times so I stick with the Aussie made stuff. I'd like to try the new IMR Enduron powders but will probably never see them out here in Australia.
