Thread: Random pressure signs?

I get this all the time in the cold. When I am hunting in the snow some of my loads stamp like a bitch! Keep them in your pocket.
I have actually tested this a few years ago with 2225 and 2217 powder using ice packs and hand warmers to heat and cool rounds.
Shot at 400 and had higher velocity’s,higher point of impact and pressure signs on the brass on the cold rounds
