How hot is a hot barrel? At what point do you set your gun aside to let it cool down? Besides the changes in accuracy associated with barrel temperature, what other concerns are there with shooting a hot barrel? I have a .30-06 Husquavarna from the late '50's that shots best when hot. You can hold your hand on the barrel but not for long. I have never had any education on this topic. Nor have I seen any discussion of it on any of the board.
