Once every couple of weeks when I pass through a city or suburb, I stop at a Wal-Mart, usually a super center. I pick up some fresh fruit, some dog and cat food, paper for the printer, and then I check out the ammo. Wal-Mart is very interesting in this regard. Some Wal-Marts have no ammunition section at all. Others have a small glass enclosures with ammo in the sporting goods section. Once in awhile, there is one which has quite a selection, including 556, 7.62x54, 380, 7mm. etc. They do stock some of the cheaper rounds, but they also stock some unusual things you would think they might not have. Yesterday, they had three different calibers of Federal brand aluminum jacketed ammo. Fifty rounds of aluminum jacketed was just under fifteen dollars. I bought some and hope to target shoot with them this weekend.

As you might guess from the price, aluminum ammo is much cheaper to produce than brass jacketed varieties. Aluminum is also one third of the weight of brass. This can be important if you need to carry a fair amount of ammo. Of interest to me primarily is the lower cost which makes my practicing on the farm much more possible. Some of the people I know really like aluminum ammo. Others don't like it as much. However, the military actually considered commissioning and replacing their brass ammo with aluminum in order to save money. No one knows why this wasn't done, but it's likely a combination of their not really needing to save money, after all, they have ours, and in part, due to a strong brass lobbying body who doesn't want to see brass prices diminish when demand decreases. Copper is stronger than aluminum initially, but in a Univ. of Ohio study, aluminum was 32 times stronger, and copper softened sooner than aluminum.
Others have also said that aluminum is not as heat stable as these other metals. For most of us with standard pistols this should not be a problem. The one clear negative is that unlike brass, the aluminum casings cannot be reloaded. Still, buying cheaper ammo that we collect and don't reload is of interest to me. Aluminum should not be a problem for your weapon either, and is not considered to be dirty ammunition.
To make sure you don't have any problems, you should always inspect all ammo for deformities before loading them in your magazine. Clean your weapon after each use to avoid the build up of any coatings that could "gum up" the internal workings of your weapon. If you shoot at a gun range, make sure they allow aluminum cased rounds. Most ranges collect the brass casings for reload and don't wish to separate them from aluminum. They want to make a bit more money after you leave.
