Blending different batches of powder?

I have a bunch of containers of each of the powders I use, and many are from different lots/batches. Some I purchased recently, some I've had for several years, and at least two cans I got from a friend and they are probably 10 years old.

I'm in a position to work up several new loads with new (to me) rifles, and at the moment have no need to load any more of a known load from a known batch for an existing rifle.

I'm thinking of just taking all of each type of powder and blending it together, so as to have one bulk jug of each type, and thus avoiding inconsistencies in my loads when I empty one can/jug and move on to the next. Instead of having a number of 1lb cans from various lots, I'd end up with about 10lb of each type, blended.

Any feedback?

Just to be clear, I'm not suggesting mixing different types of powder, only different lots of the same powder.
 
Get yourself a large bowl and fly at it. Spend enough time mixing to blend all the different batches together and you will be good to go.

I suggest you take a felt marker and black out the batch numbers on the jugs before you refill them.

I have done this for many years.
Often it was impossible to buy multiple containers of one powder type that were all one lot number.

So as not to hve to work up a new load with each lot number, mixing them makes sense.
You now have one larger lot that is consistent throughout.

Thanks gents; I couldn't really think of any downside to this, but wondered if anyone had experienced something odd by doing so.
 
Mixing different lots of the same kind of powderis A ok such as a 10 yr old 1/2 pound of 4895 and a half pound you bought last week,
NOW, mixing different amounts of different leftover powders is only a good recipe for fertilizer in your garden. Once you have carefully mixed all your old ounces of all your old powders together in a large plastic bucket or bowl, then carefully spread it over your lawn, water it, and fugedaboudit.
