I have heard differing opinions on storing loaded magazines. Some folks recommend not doing this because of damage to the springs. Others say it is not a problem because the newer magazines (springs) are built to stay compressed for a long period of time without losing their original pressure. I am curious on what other people are doing. Are you storing your high capacity magazines (15 or greater rounds) fully loaded? If so, do you empty them on a regular basis and rotate through other magizines? Would appreciate advice from others on maximizing the life of my mags. Thanks.
