27hand: If you have a gun which is well-manufactured, with very good quality control,
I'll shoot it in +5* F (with no wind). or 104 * F.
During 33 years of frequent "business layovers" up north (via our MSP and DTW hubs) I always took the clothing to allow jogging outside: Bismarck, Grand Forks, Duluth, Grand Rapids (not so cold), Buffalo, Rochester NY etc.
