[QUOTE="Marble, post: 1079840, member: 51354"] Just to elliminate temperature variations, you can keep your ammo in a small ice chest. I've done this before in 90+ heat to keep my rounds at the approximate temp. If it's going to be warm outside, I will place the cartridges in my ice chest with a piece of cardboard over the top of them. On top I might stick some cool bottles of water there or an ice pack depending on what I expect to encounter while I am there. Prior to doing this, if I was out in the heat for several hours, my velocities would slowly climb up. They have stayed more consitant since doing this in cool weather. If you were shooting in cool weather before, and now in hot weather, I would imagine the extra heat may give you a different pressure or velocity. Do you have your velocities still from when you shot in cooler weather? Be interesting to see if they have creeped up. [/QUOTE]
