Well, I figured there were math equations that delt with this cold constriction.
However, I was referring to -40 ambient and colder. Not 30 below. There is quite a difference between -30°F and -40° F or C .
There always seems to be those that will push boundaries with things . Like long range shooting or being out in the cold ( just because most people say its too cold)
Blown primers, ruined brass and velocities of 400 fps more than normal were my instructors in this.
Once the firearm had warmed up, the velocities dropped steadily as the barrel warmed . Velocities dropped below normal above freezing temps by the last shot in the mag or cylinder( revolver) . Indicating the powder was still at or near the 40 below or colder temp.
I didn't figure it out on a chart , I did it with different firearms, a chronograph( that I kept warm by putting it in a box with heated towels under and along its sides.)
I Chronographed from my back porch using my woodshed with cords of firewood stacked in it as my bullet trap.
My experience is that in true cold temperatures ( -40 and colder ambient) .
Caution should be used when shooting.
Surely most people on here are familiar with using a torch to warm up froze on nuts , ratchet chain binders , threaded locker dog down systems ect.
Just a little heat from a small propane torch will make them expand enough to often times be unscrewed by hand. Instead of using a 3 foot cheater bar on a dog handle, binder or wrench.
