Ok guys I need your opinion and help on this. My place of employment does not allow concealed carry inside the building, however, we are allowed to keep firearms in our vehicle in the parking lot. My problem with this is it gets hot inside my car( car color is black so it soaks in the heat ). My worry is when it gets up to 105+ degrees inside my car how bad is it on the ammo? I know good quality carry ammo is supposed to be good at being in extreme temperature changes. Typical iwb carry in the summer It’s exposed to body heat, sweat, and winter freezing temperatures. I know that it’s good to rotate your carry ammo for this reason. Ok here’s what I do so let me know if you think it’s a good idea or not. I leave my firearm in the car but I unload it and carry my mags inside work in my bag. That way my ammo stays in room temp environment. Which brings my next worry, when I leave work I load my firearm back. So does that hurt the ammo as in bullet setback and increase the pressure in the cartridge? I carry Hornady critical defense 9mm as my ammo. It does have the cannelure to supposedly help with the setback of constant loading unloading the same round over and over. So what do you guys recommend? Leave the ammo in the hot car or continue loading unloading as I currently am doin?
