Humidity is an environmental factor as is heat to pressure on loads. It will dampen powder but very quickly dry out once the bullet is seated. The case heats up and dries the powder that was affected by the humidity. Try loading some damp powder in a case. Let the loaded case set in the warmth for a few hours and pull the bullet. You'll see how powder will be dry again.
It only make sense if your powder has absorbed moisture your charge will be off.On the subject of how moisture affects powder, there was a very good article published in Precision Shooting magazine a few years back. The way that the testing was done was very straightforward and reproducible. Moisture has a big effect on velocity. There has been a lot of unscientific guessing in this thread that does not jibe with the results of that testing.
It's not an issue when you label your bottles with the powder that's in them. Capping the bottles and trickler works for keeping out debris. Not the very best solution for keeping out moisture, but it works fairly well. Obviously forgetting what powder is in them certainly is very likely when not labeled. Using common sense should be a factor. Obviously it's not.There was a (now-deleted) post in this thread: "I leave powder in my trickler for months. Also powder measures have powder in them as well for months at a time and they are not air tight."
For safety reasons we adamantly recommend against this practice.
Do NOT leave powder in tricklers and powder measures for long periods.
The reason is not primarily about humidity. It is about SAFETY. After a period of time the loader may forget what powder is in the trickler or the powder measure. H4198 looks almost exactly like H4350. But they are very different!
Hand-loaders who forget they had pistol powder in their measure or powder dispenser have suffered very serious injuries.
For this reason we always recommend that, after a loading session, return the powder to the correct, original labeled container, and then close the lid.
You only have to make this mistake once to lose an eye, lose a hand...
Some people put a post-in note INSIDE the powder measure bottle indicating what powder is inside. That's not unwise, but the better practice is to restore your powder to its original bottle promptly after every loading session.

Piece of tape with date writen, tells me when I purchased.
Also write down date of last use, label on jug.
