How long can one store fully loaded mags without harming the spring etc.? Is it better to load 25 rds into a 30 rd mag or something?

Before someone says it, yes I realize i Could just keep stripper clips around but lets just concentrate on my questions shall we? [smiley]

Thanks.

I hear that 28 rounds can be left loaded indefinitely.  This from a guy who knows his stuff, but I don't know his source so YMMV.

I usually keep 8 or 10 30 rounders fully loaded - for up to 6 months at a time and have never had a problem.

Most standard-capacity military and factory mags can be fully loaded indefinitely without any problem.  One of the reasons these mags cost more than aftermarket mags is because of the superior engineering and materials quality used in their manufacture.  This certainly applies to USGI AR mags.

Aftermarket mags cost less because inferior parts are used.  Cheap springs, poor heat treatments, and other problems aren't obvious to the novice, but the problems show up eventually.  These mags should not be left fully loaded.  Downloading by a few rounds will probably prevent most problems.

Klinton-reduced 10-rounders are ironically some of the worst mags to leave fully loaded.  Due to ATF regulations, these mags have to be made so that the springs are over compressed when fully loaded.  This is why new 10-rounders often have problems with the ammo not being stripped off the mag.  In most cases, you're better off downloading these mags by 1 round.
