In the Great Lakes region, it can be 60°F one day and 0° the next morning. Probably the coldest with the muzz would be around -12°F, using BH or T7 and saboted bullets. The coldest days are the best hunting days, as it brings whitetails out early to feed in the afternoon.

Coldest I've ever hunted period? Whitetails in Saskatchewan at -20°F with 20-25mph winds. Warmest it ever got on that entire trip, -5°F and it felt like a heat wave compared to -20 and the wind! You'll learn what cold is in northern Saskatchewan.........
