It's probably just all in my head but I feel like if I load them up and store them the springs will give some. Like I said it's probably bullsh**. I have one or two for my 5.56 and two for 6.8 and one for the AR 10 and I am comfortable with that. Now I have several loaded up 1911's an a loaded recover with speed loaders on hand. I think that will about cover home defense. I am not expecting a all out ground assault any time in the near future..I have piece of mind that I have new mags in the package with springs in the relaxed position. Like I say so don't start kicking me around like a leper I have no provable theory on that one.
