    Default H322 and cold weather

    I can't remember for sure, but I was thinking I had heard something about H322 not responding real well to cold weather. Does anybody know? What powders are the best "all temp" powders?

    I used it in 6.8mm SPC down to 15 below zero and it worked just fine. In fact it is the best powder for the 110 grain bullets in the 6.8mm.

    Hodgdon Extream Powders are designed just for temperture stability and H322 is an extream hodgdon powder. Mag primers are one trick used for extream cold temps.
