I generally avoid shooting loads down below 5000 psi in the depths of winter.


A lot of the older reloading manuals will note that the lower pressure formulas they provide are not good cold weather loads. I don't know what the low noise-low recoil factory loads generate for pressure, but I do know that I've heard very "poofy" reports (not just less noise) on days when it's freezing or a little below.
