I am getting back into reloading after a LONG absence. I have several part lbs of old powder ($14 and $16 /lb). On can is 4064. I have a number of loaded 270's. In the reloaded box of ammo it says 48grains of 4064. I have lost my old reloading data so all I have is what was labelled in the box. I pulled the bullets from 3 and it all measures 48 grains and the powder is a fine, extruded stick powder, SHINY black. I opened the can of 4064 and it is identical physically, but the color is tan. About the same color as Varget. If it was shiny black I would say, YES, that is it. My question is, what color should 4064 be and does powder change color with age? I opened a can of 4831 of the older vintage in the old paper can and it is shiny black just like the powder in the cartridges, just larger physically. I don't want to buy a can of 4064 just to see the color but want to duplicate the load that I have loaded. I have no reason to believe that the information in the box is incorrect or has gotten mixed up with anything else. I opened another partial can, of 4350, same vintage, and it looks they same size as the 4064 and is the same tannish color. Anyone know the color of 4350? Thanks. Any help would be greatly appreciated.
