Yesterday I finished my first 8lb jug of X-terminator rifle powder. I had a second that I opened up. Instead of using it I thought I would try loading some rounds with a different powder. So the little bit of X-terminator that was left in the powder measure I dumped in the new jug of X-terminator. Did I make a mistake and ruin the 2nd jug? I read somewhere about never mixing powders because even though they are the same make they could be from different lots. So did I mess up or should it be fine? Forgive me if this is a stupid question I tend to worry about these things.
