    How long before you swap out old ammo?

    Hey guys I have had my Remington 9mm Golden Saber rounds in my gun for a few months now and am noticing that they are getting faded and are just looking old. How long do you guys leave the ammo in your magazines before you swap it out for new ammo?
    The only time you can have too much ammo is in water or in fire

    Tarnished brass casings? No problem.
    I used to regularly change out my PD ammo twice a year. Like shoot it up and re-supply. Thing is, it really doesn't need to be done unless you've run them through the chamber IMO. Environmental factors will play a more important role in you deciding what "looks old" and what needs to be disposed of (at the range). I'm sure I've got a few magazines full with 1 year+ on them. Heck, I've got so many, they're actually hard to keep up with anymore. Thing is, whether the ammo is in the box and stored for 5 years, or kept in the magazine under environmental variables matters little. Looks aint everything. Some of my Speer 124gr+p are over 10 years old in the box. When I take them out of the box and load them in a magazine, I consider them fresh. Even the nickel plated cases will tarnish over time exposed to the elements. This doesn't indicate any deterioration of the cartridge. Short answer, shoot 'em and replace them as you feel necessary.
    Or....when you feel you can afford to re-supply your old ammo with new. As the case may be.

    Two to three times a year.

    I also make it a point not to chamber the same round more than 3 times or so; after the third chambering, it goes into a range only mag.

    About every 3-4 months. And when I do, I shoot them in addition to the practice rds. during practice.

    well in about a month I'll be getting free carry ammo from my department so once that happens I am sure I will be able to change it out more but I was just wondering. Usually for my rifle ammo tarnished casing never really bothered as I would only use them for the range but since I am now CC I was curious if anyone had any bad experiences with older ammo.

    About every 10 years. Ammo stored in a cool dry place will be good 50 years from now.

    You mean the taxpayers will be changing out your ammo when you feel the need. Then by all means, when it don't look shiny any more, change it! That's exactly what I would do.

    every 6 months, i don't understand how chambering the same round a few times can mess things up

    When on the street I changed every three months or so shot up the old and replaced it. As stated the exposure to the enviroment and elements is what can degrade ammo over time sitting in a box or mag on the shelf not a problem.
    INccwchris chambering the same round over and over can cause the bullet to be pushed back into the case causing excessive pressure when fired. An easy check is to empty the mag and stand the rounds up and check to make sure they are the same overall length, if you find one that is shorter than others by a significant amount trash it.

    About every 8 to 10 years.

    I just shot some 9mm ammo from the Spanish Civil War earlier this summer. It was stored in a hot attic for at least 40 of those years.

    They all went bang.

    If setback isn't an issue, I don't worry about it.

    It can cause bullet setback, which may cause an increase in pressure when fired.
    As an experiment (and to prove it to myself), I rechambered a .45 ACP 230 grn Gold Dot, a 230 grn PDX1, and a 230 grn LRN reload 10 times each. The PDX1 set back the least, .003". The Gold Dot set back .025". The reload set back the most, .03", but I expected more since the case has been refired several times and I don't crimp real tightly.

    I don't have any schedule for using up ammo. I've not seen any corrosion indications on carried ammo. It's basicly good forever. I avoid rechambering the same shell over and over, especially after seeing the results of my own experiment. The only time my carry ammo is rechambered is after emptying the gun for a trip to the range or cleaning, and even then, I scramble the rounds in the mag..

    My carry ammo gets exchanged for fresh, new, ammo about once a year. It probably doesn't need it, but I do it anyway.

    Wow! I am in the minority. I shoot mine out every 7-10 days.
