if properly stored they´ll not be affected, and certainly not within a year.

You're right. Primers do lose consistancy over time. But the effect is less noticable the closer one is to the target. It's at ranges greater than 500 yards that their uniformity starts being noticed. And then only by folks and hardware that shoot real accurate.

At a hundred yards, one won't notice any difference. But then one can meter powder charges directly into cases primed with most anything and shoot groups in the ones, too, at 100 yards. Can't do that at 1000 yards; gotta weigh powder charges and have very consistant primers to be accurate at that range.

I had some that were over 5 yrs old (Fed 215M) and they worked great and the load data never changed.

But one day in the late summer down here in south Louisiana my AC gave out and my house heated up realy well throughout the day , well when I got home and finaly got the AC guy out to fix my unit the house tem was in the low 100 deg range and the hunididty down here stays in the 80+% range , well we got the AC going and it ran all night till it cooled the house down , I noticed that their was some condinsate on some stuff but the folowing weekend I loaded some ammo and all my primers were FUBAR from the drastic humididty and temp change.

But so long as they stay dry they should last for years and years

Could you post a picture of this, I am guessing it is somewhat more vertical than a bughole. [img]/ubbthreads/images/graemlins/cool.gif[/img]
