Last year, I cleared the breech by firing a round into a target after a late-season hunt with temps about 10F. I was shooting a Traditions break action muzzleloader with pellet charge square sticks by Jim Shockley. The gun was very cold and when I fired it there was a very subdued, almost silent report. It was late and I could almost watch the bullet go to the target; it almost seemed slower. But it did not drop much. Another fellow I know had a similar experience hunting cold weather of a subdued report and he stated that the bullet fell short and he missed a nice buck.

Will extreme cold affect performance?
