[B. Lahey]

Around two years ago I got to questioning the widely held belief that the springs in common drum magazines will weaken over time if left loaded. That notion is undoubtedly incorrect regarding box mags, so I figured I would do a small-scale test of kalashnikov drums (75rd top-loading of eastern-euro manufacture, to be precise).

So I loaded up two of them and forgot about them until last weekend when I randomly rediscovered them while pawing through my ammo closet.

I took one to the range and it ran just fine. I think I'll let the other one sit for another year or more before testing.

So there you go. Probably not a big enough sample to be very meaningful, but still an interesting result against the conventional wisdom.
