I've had my AR mags loaded with 223 for quite a while now, over 2+ years. I want to empty them and replace with 5.56. After unloading the 223 ammo should I wait before I reload with the 5.56 to give the spring any rest ?

Do you jack your car up every two years to give it a rest?

I don't fully load my car so that the springs are always compressed, so what's your point ?

You leave your car jacked up so that the springs are not compressed?

Springs get fatigue from being compressed and relaxed, not from being compressed and left alone.

Wasn't sure if having them compressed for quite a while, releasing them, and re-compressing them that same day would create a problem ?

You're fine. All my good ammo is in .223 anyway. My 5.56 is usually FMJ range ammo.

Give them a glass of wine to speed up the relaxing.  Then you can stuff your boolits into their little slits with abandon.

My cars don't float, their springs are always compressed. Springs degrade from cycling, not a constant load that it's designed to handle.

Better splainin than me.

They're designed to be cycled thousands of times.

The tires, not the springs.

Is there any subject that can be posted on here that doesn't end up being a comedy routine ?

I for one am ecstatic to see this subject come up on a holiday.

Especially this holiday.

Traffic on this site should be high today.....Lending to the potential for yet another EPIC spring thread.

Who knew you could  get so much entertainment from such a simple subject?

But seriously, I'de give them a full 8 hours of rest before putting them to work again. Also, feed and water them so it is ready for the next two years

Steel has what's called a fatigue limit. That means you can cycle it indefinitely and it won't break, as long as you don't go over about half the tensile strength. The spring has many coils by design, so each section of wire is only stressed a small amount, far below the fatigue limit. What kills mag springs is corrosion and over compression. You aren't over compressing it. If there isn't any rust on it, then it should last forever.

At least I won't need to fertilize them, not after all the bullish*t from this thread.
