Mixing diferent Lots of the same Powder

[Adam Helmer]

Westerner,

Billy gave the right answer. I have poured powder from a can into another can of the same manufacturer, type and SAME LOT NUMBER. I would use a can at a time and then not have your problem of several cans of the same make powder partially full.

If I run out of a can of powder and go to another full can of the same powder, but a different LOT #, I mark the old powder charged and loaded cases with a swipe across the primer with a black magic marker and shoot those few rounds for practice.
