No, I wouldn't blame you at all, and in fact I finally started doing the same thing in the past six months or so, because often even the powder companies didn't have any of some powders--especially handgun powders.
That still doesn't change the fact that the problem is primarily due to far more demand than normal. I started buying some kinds of powder wherever I could, because so many other shooters continued to, for so long, that I had no choice. But I have had to plainly state in some magazine articles that XYZ powder wasnt tried because none was available.
