Finally, someone making sense.
"...heat ...vibrations ...last for a while then fall off" ??
Firstly this is a solution for your own rifle only!
In the case of my first N. trapline rifle. an old Rem pump with undrilled receiver, I JB welded a pivot mount and front site on this rifle. Since then it has been carried on horseback (bucked off once thanks to wolf on path), Argo, canoe and snowmobile. Notice the shiny 0% blueing finish? That doesn't come from hanging on the gun rack!
Will fall off in time? Yeh, I don't think so. That was 1970 when I mounted that scope! My secret is to roughen up the surfaces (see quote) and use MEK (methyl ethyl keytone) as cleaner.
