Powder Temperature stability.

[pds]

I found the following info regarding temperature stability of powders available for handloaders. I found it in the 6.5 Creedmoor forum. Poster said it came from the sniperhide site. It shows velocity change per one degree temperature change for different powders. I cannot verify how accurate it maybe:

I wonder where CFE 223 would fall on that scale.

Excellent post PDS. And people wonder why Varget, H4350, and H4831 are in such high demand.

My suspicion is that CFE is somewhere closer to 1fps/*

PDS did a test with it using a freezer and a hot day and posted the results here.

Now I'm curious.

Has anyone tried using Varget with the 100gr and lighter bullets. I understand (have always excepted what I've read) we can't get enough into the case for the 120gr+ bullets, but has anyone tried to use it for the lighter bullets?
