Actually the entire discussion has been about mag and recoil springs with scant attention paid to temperature. It's not been an important point of focus. The phrase "at room temperature" was seldom mentioned and has NEVER been a key part of any of the comments I've made in this discussion. (I don't think I've ever mentioned it...) I can understand how a recoil spring COULD get pretty warm, with use, but not so warm as to affect the temper/strength of the metal. A gun THAT hot is not a gun I want to hold in my hand. I did NOT consider it a point of discussion.
I apparently misunderstood an important point about spring compression, and you set me straight. You said, in effect, that depressing a spring by physical displacement (using light plastic round replicas) will have the same effect on the spring as using heavier or actual rounds, as long as the springs are compressed to the same degree. If that happens -- i.e., the compression is the same -- the effect is the same.
Except for that misunderstanding (ignorance, really) on my part, the discussion has been focused on the effect of compression (or, arguably, OVER-compression) when the springs are near (or have exceeded) their elastic limit.
With coil springs, I would assume that "elastic limit" should really be considered "elastic limits," as the work is spread over many different places in the spring material. And, because MOST mag springs aren't pure coils, but hybrids, with long flat stretches of material connected to coil arcs and smaller flat stretches. It seems that these springs might act a bit like flat springs AND coil springs, and maybe with some torsion bar-like action thrown in at the corners. Recoilo springs are more typical coil springs.
Given all of that, I would expect degradation to be occur around the various corners in a mag spring, but not occur uniformly or simultaneously throughout the material. It could be a very slow process, and not even noticeable at first. With a recoil spring I might expect to see degradation to occur where compression first occurs... But, maybe I have all of that wrong, too. It won't be the first time I've had it all wrong. I've learned a lot from these discussions, and it seems worth the effort.
