Went to the range today to, among other things, function test the GP100 I picked up the other week. I brought along some of my usual .357 ammo, but I also had a dog’s lunch of .38 Special that had been cluttering up my shelf for a while. It was a mix of factory ammo, including tracers, going back quite a ways. None of it was newer than the 1990’s and some of it, like the tracers, were well past 50 years old. (Peters went defunct just after WW2)
How’d they shoot? Well, I’d like to say it all shot fine but that’s not true. I had two failures due to light primer strikes. Both on the same brand/headstamp. I think what happened there was that the primers were seated a bit high. Both fired on the second strike. Everything else shot fine. And, yes, the tracers lit up…not 100%, but most of them. The ammo, however, did function and the bullets went downrange which is the important part.
I bring this up because there is often the question of ‘how long is ammo good for’ or ‘how long will ammo last’. In addition to today’s episode, I’ve shot stuff a hundred years old that fired no problem. Heck, I had a buncha 1950’s vintage FN .30-06 ammo a few years back that fired perfectly. The answer to the question of how long ammo will last (and by ‘last’ we mean how long will ammo perform properly) is, basicaly, forever IF stored properly…in an airtight, moisture proof container, like an ammo can.
Now, having said that, do you know where the not-optimum storage place for ammo is? Your gun. The ammo you carry around in your gun on a day-to-day basis is exposed to elements, moisture from your body, and a few other environmental factors. And it will still work just fine years down the road. However…there is no point in taking chances so I personally fire off my carry ammo every so often and replace it. Usually annually, but Im kind of a paranoid that way. You can probably swap it out every other year and be just fine. For me, though, I swap it out every year.
So there you have it…stored properly ammo, in this case some .38 Special, will last a lifetime…easily. Class dismissed.
