[QUOTE="LDHunter, post: 2875558, member: 105"] I have an alternate opinion... Why would you do load development in 100 plus degree temperatures when your elk hunt will likely be 50-100 degrees cooler? Even with Varget or similar powders that aren't temperature sensitive it would surely skew your research. Plus there's the temperature difference effects on the various metals involved not to mention steel, copper etc. Plus the material in the stock will have different characteristics even with bedding. Also I think the metallurgists would agree that uneven and/or really rapid cooling of a barrel might cause warping and possibly other changes in the metal. I'd stick with shade and fans both inside and outside the barrel with ambient temperature air. Air conditioning in the vehicle would likely not be harmful but the application of cold wet materials to a hot barrel or cold air introduced to the inside of the hot barrel smacks of serious issues in the future to me. Consider this also. Every shot lays a layer of powder fouling and at least some copper fouling inside the barrel. Imagine what that does to that layer as it becomes soupy as you rapidly cool it and condensation occurs then it's reheated and rapidly cooled and copper bullets travel through that soup at thousands of feet per second. Now compare that to a single shot from a clean or slightly fouled bore at elk hunting temperatures. LOL Just one man's opinion tempered with many years of experience and reading expert opinions.....
