Mixing different lots of powder

I have 5 pounds of Retumbo powder that are all different lot numbers. I am thinking about mixing all five 1pound containers into 1 large container and mixing them together so I don't have to adjust loads every pound. What do you think?

    I do it, think of it as just evening things out

    Unless there is a questionable lot (old, questiinable storage, etc) I'd mix 'em.

    It would probably be ok, But I personaly would not mix different lot numbers or even the same lot
    numbers for several reasons=

    I would use out of one and leave the other cans sealed to last longer.

    The other reason is that you can never get them mixed uniformely and the results may vary
    shot to shot.

    When I run out of one can I seperate the next batch of loads to verify the velocity of the new
    can/lot of powder and then adjust the load volume accordingly. (It might only take 1/10th
    of a grain, or might not need any adjustments) but it does happen even with the same batch
    sometimes based on the age and number of times you opened the old can to humidity.

    It sounds like spliting hairs, but at long range everything effects the POI.

    I stoped buying bulk powder (8 pound+ kegs) after I found velocities falling the older the powder
    got and the more I opened it in the 90% humidity of south texas.

    Just my opinion

    Re: Mixing different lots of powder

    Can't see going to the range to verify every time I switch from pound to pound. I prefer to buy 5 or 8 lb cans or same lot number with one pound containers but that isn't always possible. I have mixed lots for years.

    After you mix them try to put the powder into containers that get filled close to the top. I think keeping out as much air as possible might help keep the powder fresh. I often combine two separate one pound containers into one container for the same reason.
