Does anyone have any loads ( have actually used them) for 0-10 degree cold weather? I like to hunt late season elk/mule deer cows and does. Our weather that time of year ( Dec to first part of February) can be -4 to 35 degree, depending on the storms we get. I'm looking at 150-175gr loads...I'll be using either Norma or RWS cases.
