    So I have a 1lb container of AA#5 and an 8lb jug as well. The 1lb container is getting close to empty and I haven't opened the 8lb jug yet. I'm thinking that it might be best to transfer some powder from the larger jug to the smaller container every 1000 rounds or so in an effort to open the larger jug as infrequently as possible.

    So the question is really 2 parts:

    1. Is that a horrible idea? I'm thinking the downside is that there may be slight differences in the powder from one lot to the next and it might not be a good idea for the powders to mix, even though they're both AA#5.

    2. Would it be beneficial at all? Can having the big jug open a bunch of times (albeit for extremely short periods of time) and dumping the unused powder back in over and over cause it to not last as long as if I only opened it to refill the 1lb container? Of course there's the obvious benefit of a 1lb container being easier to work with than a large and heavier jug, but I'm more worried about the life of the powder than anything.

    My reloading bench is in my cool, dry basement so I'm thinking it might not make much of a difference. Thoughts?

    I want to also make clear that I would never put powder in a container that is not marked for that powder. For instance, I would never put AA#5 powder in an old empty AA#2 jug, or even in some container that was originally used for something other than powder.

    What I do is when the 1 lbs. container gets low. I open the larger container of powder and make sure it meters out the same. If it is I then poor the small amount into the larger container and shake it around. I then fill the 1lbs. container from the large jug. It just makes it a lot easier to work with.

    In my decades now of reloading, I have rarely seen a lot to lot change in powder that was dangerous to use my exist data with. Now granted, I do rarely push the top end anymore, when I do, I back off & work back to max, but that is jmo. So I keep 1# containers around to refill from my 8# jugs. The 1# are just easier to handle aroun the bench. You shoud be fine doing this as well.

    Schrag4,

    I have taken powder from a 4lb container and put it into an empty 1lb container (in my case they were Hodgdon Universal), in order to make working easier.

    I have never mixed powder and generally don't think it is a very good idea to do so. Will the world come to an end? No, but as a matter of safety and my own self imposed rules i just don't mix powder as you have stated.

    Good luck and be safe out there

    Yup. That's how I do it too. The big container is too unwieldy when loading the hopper.

    Note; we are NOT talking about mixing diff powders, should never be done. Mixing small amounts of say Unique, with a new jug of Unique is NOT going to have any affect on your data. Again, if you are using max data, then it's always prudent to drop 5% & work it back up. That is true whether changing primers or cases when at the top end.

    Solo 1000 has a pretty wide spread from lot to lot. I don't mix them because I just want to chrono the new lot and see if I need more or less. I do mix that last little bit and use it for practice ammo. I won't matter.

    I always transfer from a big jug to a smaller (usually 1lb) bottle. When I have poured the last bit from the small bottle into the hopper and still need more, I then transfer from the large jug to the smaller bottle. I also keep the jugs in an air conditioned dry room, the 1lb'ers are in a cupboard above the loading bench in my garage.


    I have never worried about mixing powders from bottles of the same label, regardless of lot.

    a while back i got a good deal on 3 1 lb bottles of accurate 2230, i had an 8 lb bottle of 2230 that was more than half empty i dumped all of them together and shuck it all up so that i only had one container to keep.

    I have only one time had a lot of powder that was different from a another lot of the same kind and it was VV. Not much maybe .2 or .3 difference.

    Fred "we are NOT talking about mixing diff powders, should never be done..."

    Sorry Fred, perhaps I did not make myself very clear. I agree different powders should NEVER be mixed. What I was referring to was mixing one batch of powder with the same powder from a different batch.

    As I stated before I agree that you very well may end up with the same numbers and no terrible after effects. I just don't do that myself - just my choice.

    Accurate powder have switched manufacturers in recent years. The stuff made in USA is totally different than the stuff made in Belgium a few years ago. It doesnt event look the same. Those I would not mix. Otherwise a small amount of the same tyoe of powder well mixed into a larger container isn't going to hurt anything.

    Horrible idea?, no. Beneficial, yes as its easier to work with the smaller containers.


    I also don't worry with differing lot numbers. Actually, I don't believe I've even checked lot numbers on powder in the last 5-6 years.

    I would just be sure that the container is marked ONLY with the type of powder that is in it. It would be scary to put Bullseye in a Longshot container and make that mistake because you didn't notice the Grease Pencil mark on the container and loaded up the Bullseye as if it was Longshot.

    The Belgian stuff was super tiny spheres. The USA made powder still meters as well but it is more irregulalry shaped. A mix of tiny spheres and flattened spheres. Different color. Darker and shinier.

    Wow, Those tiny spheres were one of my favorite things about AA powders. Thanks for the info.

    Thankfully the metering superiority hasn't changed at all.

    This thread shows photos of A9 before and after. A9 and A7 Belgian and American lots were/are the same shape and size. A5 is American made too and it is the same shape as A9/7. Scroll down to the Shadow's post number 8.
