Reloading Aluminum Cases

I know you are not supposed to reload aluminum cases, but why? Is it the physical properties of aluminum that donít allow it to be resized? :confused:

pretty sure you'll get them stuck in your dies on the first try. Alum cases are severely compromised after you shoot them once. Al corrodes exponentially faster than steel in high heat environments. When you expose Al to heat Oxygen and Sulfur and Carbon, especially when it is so thin, it's pretty much FNG (F..... No Good).
If you're extremely careful you may be able to reload them, I know you aren't supposed to, don't know why you would want to, I've had new ones rupture in my guns before, nothing huge but it's a PITA to get a cracked Al case out of your gun after it has flash welded it's self in.
I despise them myself.

If you are talking about the Blazer ammo by CCI;
They use an odd sized "Berdan" type primer. The anvil is in the case.
The primers are unavailable commmercially. Hence, reloading is not an option, unless you are in a "desperate" situation. Then, you could feasably drill the cases to remove the anvil and enlarge the primer pocket to take a standard primer. But why you'd be in this situation is unimaginable.

Best bet with the aluminum cases is to bag them along with your empty soda cans and sell them to a recycler. Then take the money and buy some of the Winchester "Value" packs of ammo. Then, you can reload the emptys.

+1, on the primers. One of my friends told me about those a while ago, maybe they do that so you can't reload them.

Aluminum isn`t as "malleable" as brass and you risk case splitting if you reload them. Speer has used warnings and odd primers to discourage attempts, heed them, they are there for a reason.

What Ol' Joe is saying is that aluminum doesn't like to be bent too often. Once or twice and it breaks. Same thing when it's expanded and you resize it. That is bent once.......:D

Yep! there's a bunch of good reasons why Speer uses non-standard primer sizes and Berdan to prevent them being reloaded.

do not load allum cases!!after firing they get brittle and you can squez them
and they crack and breakup.i picked up a number of them to police the area,and they broke in my hand.thats why they are berdan us do not try to reload them

Aluminum is a cheaper and more ecologically sound alternative to useing steel cases in your gun. It will work, but has more issues involved in it use then a normal brass cased round usually will.

Aluminum cases will last one and only one expansion/de-expansion cycle in a chamber. They expand well but the heating and expansion from being used changes the crystaline structure of the material.

For best ideology in a simple way think this: aluminum cans and cartridge cases only work for the first usage,hence you cant it back to coors or CCI for a refill. But with a glass(metal) one you can.

Why would you want to anything that is wrong enough to put
yourself at risk. Seems to me they used to mark on the boxes
thta fact and use odd size Berdan primers to ensure that you
don't want to go there. Yep, I know those who do steel rifle
cases and a failure can be quite devestating to save a few cents:mad:

it doesn't have the malleability of brass...

I reloaded some Aluminum, this was the first and only one I shot. Bullet was projected the casing was ejected. I bent over picked up the casing and decided against shooting the rest of the shells, they are now a nice display on my shelf.

Trueblue1776: point of clarification sir,

The correct abbreviation for "no ... good" is NFG.

FNG refers to "... new guy."
