The powder is junk in cold weather
Shot my deer at zero degrees this year.
Knight Disc Elite 45
110 grains of BH 209
200 SST
Winchester 209
I've never had a FTF with BH 209. I must admit that zero degrees is the coldest test I hope I ever have.
Be sure to use shotgun 209s. Not the ones weakened for MZ use like the T7 primers or Thompson center primers. These were weakened to avoid the T7 crud ring.
