I just bought a 2000 round case of IMI +P+ 9mm from http://www.southernammo.com/products/products.htm#ammopistol $159.00 per case plus shipping. I've been watching their site for several months waiting for them to get more of that .308 and .223...no luck so far.

IMI told Southern Ammunition it was non-corrosive. After checking it, they weren't sure so they're selling it as corrosive.

It's Boxer primed. Can corrosive brass be reloaded? If so, is there any additional procedures to be carried out?

Thanks, people!

As long as the primers don't use mercury compounds, there isn't a problem with reloading the cases; just treat them normally as far as tumbling them clean and resizing etc.. If there are mercury compunds in the primers, the mercury is released upon firing the cartridge and will dissolve into the brass metal the case is formed from, which causes the brass to become weak and brittle.
Corrosive primers are usually chorate compounds, which after firing result in salts that will pull humidity from the air to cause the rust. Thats why when cleaning after using corrosive primers you should use a couple of patches with hot water last, first using standard solvents to remove the powder & copper fouling. The hot water will immediately dissolve the harmful salts and remove them, the standard oil-type solvents do a very poor job as they can't dissolve these salts. Use the hot water last so that any salts trapped under the powder & copper fouling will also be removed, then dry and oil the bore to prevent rust.

It's the primer that's corrosive in case you didn't know that already. If this stuff has been loaded in the last few years I can't see how they claim it's corrosive. I'm sure stranger thaings can happen but most modern countries don't use corrosive primers any more. If it's boxer primed it's reloadable.

You can test them yourself when you get the ammo.

I clicked on the link and my computer shut down. Anyone else have that problem?

If I remember right IMI is Israeli Military Industries, and I can't imagine them using corrosive primers in anything made in the last couple of decades or more.
