So, a bunch of my buddies came by today and we were shooting all kinds of stuff. My question is this......two different rounds in particular.... We shot a 416 Rigby a bunch and a 338 Lapua a bunch........right after we shot the guns and ejected the brass you could pick up the brass and it was always cold. The brass never got warm or hot. I could never get a clear answer from my buddy......he wanted me to figure it out for myself and i just cannot figure it out or find the answer anywhere. Do any of you know why/how this happens?
