[QUOTE="Lefty7mmstw, post: 729539, member: 48043"] +1, but if you are at -10 degrees with a wind your pocket will still be at freezing. You should shoot at the temp you will be hunting at to be sure, but I realize this isn't always possible. If I couldn't hunt with a load I'd vetted in both hot and cold temps. I'd go with THE ONE THAT SHOWED THE LOWEST ACCURACY FALLOFF AS I DROP THE CHARGE WEIGHT, and I'd hope for a slight gain in accuracy. If your load is see-sawing between great and crappy accuracy as it pulls in and out of node when you pull the powder charge up, the load is crap and I won't touch it period. Don't use a mild primer either, as under igniting will cause a squib on occasion-- with a bullet in bore chance, or poor accuracy at least with long lock-time. Over- igniting with a hot primer just pushes your pressure up a bit. [/QUOTE]
