Same powder different color

[freire]

Gentleman, i was just getting ready to load some ammo, when i noticed a heavy difference in color shade from two different canisters.
Powder is SR4759, one is light grey in color the other much darker grey, any of you gents noticed this before, is it OK to continue?
Thanks
Victor.

Imr 4759 has a very distinct shape. Is the shape the same? I remember hearing that older lots burned faster but have no experience with both lots. If the shape and size is the same I would say start low and work up.

 

[oops]

I have noticed this with a verity of powders..700x comes to mind,along with IMR 4895 being most notable.Never had an issue,shot well till it was gone.

Shape is the same.

One can older than the other? The colour doesn't matter, but older powder lots may be different than newer.
