I hope I have this in the right place.

A long time ago I read something about not being able to store loaded BAR magazines longterm as the spring would be damaged. This being due to these magazines having a spring made of flat-stock wire.
I may have this wrong, but that is the way that I remember it.

Does anyone have any experiance with this, or know of a source of good information?
I have been all over the internet and read every U.S. military manual I can find. Info about a BAR is pretty scarce, and BAR magazine info is even more scarce.

What little info I have found leads me to believe that many of my magazines are late production, Vietnam era magazines. They may have a different spring than the earlier version? I have never disassembled one, and I am away from home now. When I get back i will look at all of my magazine springs.

Any help is much appreciated.
