Varget and temperature sensitivity

[GaryL]

Must be my day for informational posts.

Occasionally, I see people post that Varget is very good for insensitivity to temperature change. I came across this article which suggests more factors may play into temperature sensitivity than the powder alone.

FYI & YMMV

Very interesting article.
I might pick a nit or two about the methodology of the way the data was collected but I have no doubt that the reported effect of barrel temp is real and something Hodgdon must not have been looking at regarding their "Extreme" Powders.
