Here are another couple of options on .223 ammo for that shell eating AR-15.
The first is some Wolf Full Metal Jacket 62 gr. ammo. It is steel cased so you are not going to want to save the cases for reloading, but it is boxer primed so its non-corrosive. It is dirty to shoot, but you are going to clean your gun when you get back from the range anyway, right? This is great stuff to pick up in bulk to stash away for the zombie invasion!
You can pick this Wolf ammo up here in lots of 500 or 1000 rounds.
The next one is Fiocchi ammo and costs a little bit more than the Wolf ammo, but you get a cleaner shooting round, it is non-corrosive boxer primed, and has a reloadable brass case. This is 55 gr. Full Metal Jacket ammo.
You can pick this Fiocchi ammo up here in lots of 250, 500, and 1000 rounds.
By now you probably already know that .223 Remington and 5.56 X 45mm are the same shell. Well, actually, they are not. One has a thicker brass and a little more combustion pressure, but as far as fitting in your rifle, headspace, etc., they are the same. Just don’t try to fire a 5.56 x 45mm shell in your rifle if it is chambered for .223 Remington. Firing a .223 Remington shell in a rifle chambered for 5.56 x 45mm is okay though.
This ammo can come in a military style tin in 500 round amounts similar to the picture. it is a good ammo to stock up on if you have a traditional AR-15.
I have located a place where you can still get this in the Wolf ammo 500 round tins. It is 55 gr. Full Metal Jacket and you can pick it up here.
Note that as of 2/10/09, I checked this link and there is a 1 to 2 week backorder on this.
