Springs working within their elestic limits are not damaged by being loaded or by repetitive motion (as long as heat is allowed to dissipate).
This is so very wrong and goes against every credible source. Not meaning to be harsh... but its wrong.

When shooting mid-range loads this would be true but firing full power loads is quite another
What the.....? A coincidence at best.

Why don't you explain how the load of a cartridge (the bullet weight, powder used, and even the primer used) affects mag springs...

Don't tell us about your 50+ years of collecting, shooting, and hunting experience -- we've heard that before.
Yea gunotes. I'm assuming that you dont have any science to explain it based on your past posts so...Please... Please use your 50+ yrs experience to explain that one. On second thought. PLEASE spare us.

Properly made, designed, and maintained springs don't wear out, unless they are stressed past their elastic limits.
I agree in loose/general terms. HOWEVER, people seem to not realize that in order to get the smaller packages the consumer wants, the springs could be designed to be an expendable item.

Who's definition of "properly designed" are we using? Our desires or the designers practical limitations?


Creep/sag/viscoelastic deformation.... call it what want. The fact is:
"All materials exhibit some viscoelastic response. In common metals such as steel or aluminum, as well as in quartz, at room temperature and at small strain, the behavior does not deviate much from linear elasticity. Synthetic polymers, wood, and human tissue as well as metals at high temperature display significant viscoelastic effects. In some applications, even a small viscoelastic response can be significant. To be complete, an analysis or design involving such materials must incorporate their viscoelastic behavior. Knowledge of the viscoelastic response of a material is based on measurement"

Until someone posts some actual sverifiable evidence to the contrary.... there isnt any logical reason to doubt science.


The more the sping is compressed, the faster it wears. It is not a pass or fail issue that once it goes past a certain point it fails. As capacity increases in the same size mag or same capacity with a smaller mag, spring durability suffers.
