You guys are getting bent over in the rudest of fashion. Here in my area, powder runs $18 to $26 US depending on the variety. (This for IMR and Hodgdon or Alliant) All import powders are higher. I have been messing around with some Military Surplus Ball powders with 6-digit code names I can't recall. These are cheap ($8 pound in 8-pond kegs) and usually come with either load data or relative burning rates. One I have ia a spherical powder that has a burning rate the same as IMR4895 and it works well. Another is a surplus Accurate Arms powder #2200. This works well in .222 and the like but, again, only comes in 8-pound kegs for about $90 US.
Too bad you don't have access to these powders. The problem with them, if any, is lack of data. You need to have enough experience reloading to extrapolate loads based on burning rates and then carefully work from there. It's not hard, but some of the boys on this site wouldn't be up to the task, I think. ~Muir
