Having snap caps in when ejectors are tripped do little to nothing to ease stress on the ejector system. The hammers are still firing and the kickers are still slamming i to the stop plate. Snap caps have no resistance on the chamber walls.

Even when the ejector hammers are tripped, the springs are still partially compressed.

As edgar said, from a metal composition and integrity standpoint, a spring should work as new forever, in theory. We know that this is not exactly always reality, but i think it has a lot to do with a certain spring doing the job it was intended to do and not being overworked from a load standpoint.

[QUOTE=Dave Suponski;199207]Music wire springs such
as Parker main springs will lose 15 percent of their rated pressure soon after being installed. After that the rated pressure will remain fairly constant. Any designer worth his salt will always use springs with a 15/20 higher rate to compensate for this.[/QUOTE
