years ago I was shooting in competition, started out using a heavy barrel in 22/250, but one shoot switched to my 25/06 rem 700 with standard barrel, got it got, but did not realize till I picked t up again that it had melted into the mat I was using to lay on, imagine that it was pretty hot, but never knew how hot it was, should look up the info on melting point of those blue camp mats, would be interesting to see how hot it was.
