How long do you keep ammo in your mags? topped off? does it affect reliability?
Hi.
Springs do not weaken from long-term compression. It's fuddlore. What matters is compression cycles and the stress amplitude for said cycles.

wtf is up with k and posting pics with their feet....
i usually keep 17rnd 9mm glock mags at around 15, 30 rnd ak mags at around 25-27, and 33rnd glock mags at around 27

no its not fuddlore, stress amplitude cycles is relevant for fatigue failure, constant compression is relevant for creep, material properties change when constantly stressed...spring constants weaken when springs are constantly compressed....faggot

There are stories of 1911 magazines loaded in 1946 and successfully fired sixty years later.

At the stress amplitude it would be under at full compression and the storage temperature, creep will not be an issue.
The feed lips or the casings themselves will fail before the spring does.
Because this is relevant, I'm a Deputy Sheriff. My agency issues Glock 21's.
My duty mags stay fully loaded 24/7, the only time they are unloaded is once a year when I shoot the ammo in them to qualify and reload them afterward. The springs are almost as tight as they were brand new 4 years ago, and the last round is still a snug fit.
On the other hand, when we practice, we use range mags that stay at the range. These are never left loaded and are used multiple times weekly for shooting. These mags have noticeably weaker springs than my constantly loaded duty mags, and have had their springs replaced within the last 2 years.

Till I use that particular mag, up to years.
The only exception is 12ga in the vepr, since I use and empty those regularly.

Spring creep happens at such a low rate, even lower as more and more time passes, that constant compression doesn't make nearly as much of a difference as compression cycles do.

For firearms spring creep is hardly noticeably on the function. It's much more noticeable and an actual factor for airshit.

>creep
What, you think mag springs today are made of tin cans and toaster wire?
>>28462629
all studies in metallurgy show otherwise. There's zero "creep" of a spring which isn't moving and is under ordinary levels of compression.
