I may have to try that John. I was having fits with my rifle in the heat in July. Temps are a little cooler here in ME lately & it seems to have settled down. Anyhow I'm glad things have settled down for you as well.

Keith,
It's not just the 90 degrees + summer temperatures that we deal with here in south Florida. Anytime a vehicle is subject to sitting in direct sunlight for any length of time, the interior temperatures can reach 150 degrees. Any rimfire ammo transported in the non-air conditioned section of the vehicle (trunk) is subject to very intense heat, that can affect accuracy.
Even during the cooler winter months, when temps are in the mid 40's or 50's, most drivers are using the A/C systems in their vehicles during the daylight hours. My biggest concern when using a separate cooler to transport ammo only, is forgetting it a home, then showing up at a match without any ammo to shoot. John
