Good advice mercman, I know a lot of folks buy all these magazines, and pack'em up for when the SHTF. They never try them out to see if they're going to be reliable. When the "Mad Biker Zombies" are kicking in the door, is not a good time to find out you have a no joy magazine.
Yes to the above advice. I number all my mags on the floorplate. Every time I go to the range, I'll grab the next three, and use them that day. I'd sure want to know if they work properly, prior to betting your life on them. dozier
