Different lots of same gun powder?
Any more experienced handloaders out there that know if its ok to mix two different lots of green dot powder? in my pacific 366 press when the powder hopper gets down to the last 1000 or so grains the power charge weights become low so I try to keep the hopper above a certain amount. Ive mixed different lots before with no problems but I was told today by a friend that you shouldnt mix two different lots of powders even if they are the same powder. But if powders were that different from lot to lot than alliant would have to reprint new data constantly. also Im not to keen on the idea of having to trash 1000 grains of perfectly good powder.
