[QUOTE="davkrat, post: 972832, member: 6452"] You run the risk of being over pressure depending on the powder you use when taking a cool weather developed load and shooting it in summer heat. Some have posted on here to test loads by placing a few in an ice chest to cool them way down and compare the velocity and pressure signs you get. Another tip I plan to incorporate I read on here is to use some sort of CO2 compressed air or a battery powered inflatable pump to push cool air down your barrel. I've rubbed wet rags on the outside of my barrel to cool it in extreme heat. Seems when temps are in the high 90's plus you cannot cool down a barrel in any reasonable time. I shoot lots of .22 in between shots of centerfire but that can take a long time and with rimfire being so hard to find these days it's nearly impossible. [/QUOTE]
