The level of stress induced in modern coil springs is supposed to be designed to be below the plastic limit, i.e. the point at which the metal will undergo plastic yield and therefore take a set. Repeated stressing at close to the yield point can cause minimal deformation. Enough high stress cycles can cause fatigue, and fracture. Spring steel is selected to have a very high resistance to fatigue, on the order usually of several million cycles. The reason 747 wings, which routinely flap 5' at the tips, don't fall off, is because engineers know how to design for fatigue.
The level of stress induced in many old flat springs was much higher, and the failure rates were too.
Unfortunately, back many years ago, someone also invented "value engineering". Which says real basically, is the increased costs worth it, or are the savings worth the risk. So it is not worth the risk, monetary liability wise, for Boeing's engineers to buy cheaper metal to make the wings out of on a 747, but it was very probably judged worth the risk to buy gun springs that would only last 15 to 60 years in the 'normal' range of use.
What could have happened... did.

If it's an eight shot mag., then I guess six in the mag. and some loose shells handy. Don't recomend one in the chamber. Good luck and enjoy, Dogwalk

Fill 'er up! That includes the pipe! Unless you're leaving it in a salt spray test chamber she'll faithfully wait and be ready to rock and roll when you are!

Otherwise just have the Bad Guys call before they drop over. That way you can take it out of the safe, remove the trigger lock, get the ammo out of the other safe, clean the gun, load it and be ready when they sneak in!

Dan, that's what you guys in Mess-a-2-$hits need to do by law....right?

You guys always sweat the smallest $hit...... Keeping Home Defense 12ga. loaded - Spring Failure? - General Shotgun Discussion
