A friend and I were checking the zero on a couple of deer rifles last week and I am puzzled about something. As he shot his Remington 700 in 7mm Mag. I picked up his fired brass as soon as he ejected them and within seconds of firing them. I picked them up and put them in my shirt pocket. They were barely warm. He then shot a Remington semi-auto in .270 Winchester ( mod.742 I think) and when I picked up the fired .270 brass it burned a blister on my fingers. Had to be over 200 degrees. What causes this??? Anyone know?

I have shot semi autos my whole life and noticed this as well vs other types of actions

I am betting that with the semi auto because it comes out so fast and does not have any time to cool in the chamber.  I bet in bolt guns and such some of that heat is absorbed by the chamber/barrel acting as a heat sink.  No matter how fast a person thinks they can run the bolt, it is nothing like how fast it comes out of an auto chamber.

You bet. I've had hot cases come out of a Browning Auto 22 and go down my shirt cuff and sleeve and get caught under my glove!  Youch!!
