We all know it does. I had it proven to me over the past few months.
Last year in October I had tried some light .45 ACP loads. I loved the way they shot and the soft recoil. Come November when it was 40° colder those same loads wouldn't cycle my 1911 I use in matches.
Buddy told me I had loaded them too light.
I gave him a box of 100 rounds. 50 of each load. Told him to hold on to them.
Today we were at the range and it was a nice pleasant 72° out. I asked him for that box of ammo. Both loads cycled perfectly. He couldn't believe that pistol loads could be affected that much by temperature.
The powders in the loads were W231 and Vectan A1.
Now that we're in the warm part of the year here in N. Texas I'll be loading up 500 of each for shooting.
