Gonna travel across the US in late June. Probably a lot of stops and sightseeing along the way, and up to a week I'm going to have this ammo in my trunk. Perhaps in the desert heat in a parking lot for many hours at a time. Temps will get hot but I know this is done all the time. I'm not worried about detonation or Cop cars would be exploding every day. I'm more worried about degradation. Just thinking is the stuff better without a proper ammo can? Better circulation/air flow, cooling?
