On whether sensitivity to temperature is all that much of a big thing, I've never given it much thought other than to do all my load work up in the summer, uncomfortable as that may be. (100 to 110 in the shade :shock: ) Pressure sign will show up sooner but testing later in the year at arournd 70 to 75 degrees shows very little difference in velocity or point of impact. Where I hunt deer, if lucky enough to draw a tag, the coldest I've ever seen it was 30 degrees. Most of the time though temps run from about 45 in the morning to 70-75 at the hottest part of the day. On my elk hunt last December it was about 25 degrees when I shot my animal. Didn't seem to make any difference as I hit the elk and she died. :lol: Anyway, that's what has worked best for me. YMMV.
