PRB test powder temperature sensitivity.

It was IMRs new Enduron powders vs the old standby Hodgdon extreme line.
A couple points, your results may vary from theirs.
I didn't expect a huge difference since both companies are owned by the same company, or Hodgdon owns them both, I can't remeber how it is.
Really disappointed they didn't test Alliant Reloaders new powders that are supposed to be temperature stable (AR Comp r16 and r23)
Also the testing was done with a @tscustoms rifle.
