to similate the same temp you may encounter in Africa.
Have you ever been to Africa? During the normal hunting times, it's no hotter than Ohio in the Summer. In RSA in May we had ice on the water in the morning.
BTW: When I shot 1000 yards prone at Camp Perry we always kept our cartridges in the shade. If we kept a round in the chamber very long (waiting for the right wind condition), we would withdraw it and chamber another one. The hot chamber could "cook off" the round enough to miss the 10 ring vertically. All my ammo was compressed loads.
