Rotating your carry ammunition

A really interesting read about why you should not depend on ammunition that you have cycled more than a couple of times
http://modernserviceweapons.com/?p=130
C&P: Just wanted to put out a quick reminder to everyone to periodically rotate carry ammunition. Recently, there was an advisory from Gwinett County (GA) PD regarding an incident where an officer found himself in a deadly force encounter only to discover that the chambered round in his duty pistol would not fire. Fortunately, the officer?s training took over and he was able to successfully clear the malfunction and end the encounter.The round in question was examined by the manufacturer, who discovered that the primer mix had been knocked out of the primer when the round was cycled through the firearm multiple times. Two cases of the same ammunition (presumably from the same lot) were tested and functioned normally.Recently, one of my Detective partners and I were teaching at the range when three carry rounds failed to fire. We examined the firing pin strike and saw they were solid, centered strikes. We are now in the process of rotating all officers? duty ammunition, which we typically do once a year.Federal, Remington and Winchester all recommend that cartridges should not be chambered more than twice before being discarded. Bullet setback can cause pressure spikes and primers can go dead. In an AR or M4 type carbine, this is even more critical as the chambering process is very hard on the cartridge.In the end, I wouldn?t lose a ton of sleep over this, but it is good practice to regularly rotate the ammunition in your duty sidearm or carbine. This is not the area where you want to go cheap.Be safe out there!

In the Army I was taught to chamber a new round every morning before stand to in the PB.

I shoot the chambered round into the glove box every couple of months, just to make sure it is always fresh.
Sound advice. Don

Sorry, I hate to kick shoot a man in the glove box when he's down, but who could resist???

Thats one way[;)]
I rotated the gun to another party. Sold as soon as it is returned in 6 weeks. Gone but not forgotten
Until you get a new pick-up that doesn't have a hole in the glove box[:D]

In effect the officer started the encounter with an empty chamber and was able to chamber a round and win the fight. Well hell thats simply not possible.
The Lord was with him.
