Opinions differ on that question.
I had a gunsmith answer it once, and it made sense to me. He said, "a spring is a spring, if it fails because you keep it compressed, it isn't
really a spring."
Anecdotal evidence from me: my father handed down a 1950's era Remington Model 760 Gamemaster in 30-06 to me. He bought it new, he said in 1952. The
magazines (3) were never unloaded, and never failed to function through 2009.
