I shoot anywhere from 100 degrees to -30. I have been keeping my rounds in a ammo box or in my outer jacket pocket. So they are what ever the outside temp is. So in the summer i load the rounds a little bit lighter to keep pressure down. Would it be better to load to a summer temperature and then just carry the rounds in a pocket close to my body to try to keep them at 98 degrees . So i can keep that same load all year round? I get one load that works great but the change in temps messes with it enough to get to me. If its winter and the guns cold and i load right before i shoot. Will it matter that the rounds are at 98 degrees or will it shoot just like as if they were outside temp.
