Tech Tip: Keep Cartridges Horizontal During Long-Term StorageSource: The Accurate Shooter

Ever wonder why fine wine is always stored on its side? That’s not just for looks, or easier access when the sommelier (wine steward) visits the wine cellar. Wine bottles are stored horizontally, at a slight angle, to prevent the wine from oxidizing:

By intentionally storing a wine on its side, you will help keep the cork in constant contact with the wine. This will keep the cork moist, which should keep the cork from shrinking and allowing the enemy of wine, oxygen, to seep into the bottle. When oxygen comes into contact with wine the result is not good – the wine starts to oxidize and the aromas, flavors and color all begin to spoil“. — About.com



Ammunition Should Also Be Stored Horizontally
So what does wine have to do with shooting? Well, it may surprise you, but over time, our cartridges can spoil, just like wine can — though not for the same reason. We don’t have the issue of oxygen seeping past the bullet (the “cork” as it were). However, when ammunition is stored nose-up or nose down, problems can arise. In a nose-up or nose-down configuration, over a long period of time, the powder column will compress, and the powder kernels can actually break down. This can lead to erratic ignition and/or dangerous pressures.

To avoid the problems associated with powder column compression and kernel break-down during long-term storage, take the time to orient your cartridges like wine bottles, i.e. placed flat on their side. Of course, this really isn’t necessary if you burn through your ammo relatively quickly. But, if you are storing cartridges “for the long haul”, take the time to arrange them horizontally. That may require a little extra effort now, but you’ll reap the rewards down the road.
