Alliant's Steel powder may be a good powder for cold weather. Alliant says it is not effected by temperature change and it is slower burning than SR-4756 and Blue Dot powder.
I am using Steel powder in the 3" 1-1/2 oz loads I am reloading for coyotes. I got the data out of BPI's Hevi-Shot reloading manual.
Many years ago I had some 10 ga 1-5/8 oz 50 gr of Blue Dot loads give me problems when it was around 10 degrees. They were low pressure, fast loads. I switched to a 10 ga 2 oz load with Blue Dot and they shot fine on that same cold morning.
I have shot 1-3/8 oz and 1-1/2 oz lead loads in 2-3/4" Federal Gold Medal hulls with Blue Dot powder for many years and never had a problem. But most of my shooting of those loads was at above 30 degrees.
