I remember just a few years back when I would go down to the LGS and buy just a little smidgen of powder in a plastic container, say enough to load 20 rounds of some oddball loading I wanted to try. He would have everything in stock and would sell as little or as much as I wanted straight out of the jug.

Now, there's none there, and he will only sell in full bottles/jugs. No more experimenting for me.
