that is certainly one theory. Another theory is that strong compression will cause the springs to fail. As for those loaded mags, yes, some have been found to work jsut fine. Other have been found to not work at all. Way too much variation in spring design, metal quality, etc. to make broad blanket statements.WHAT WEARS SPRINGS OUT IS THE CYCLING OF THE SPRING ( USING IT ) Mags have been found fully loaded from WWII and still functioned fine without problems
