I found this at my local range yesterday. What really throws me off is how light weight the entire round is. When you shake .223 you can feel the powder shaking back and forth, but with this I cannot feel anything. The bullet is what really caught my attention. It looks like aluminum possibly?

I searched a little and found nothing for this specifically. A lot on .45 acp "WIN NT" headstamp, but the bullet is obviously not the same. I guess it stands for non-toxic, maybe thats why it's aluminum?

Good one. I feel pretty stupid for being so excited about it. I still dont understand why the powder feels nonexistent. Just have to pull it apart...

Depends on the type of powder being used and the charge that used. If the powder being used fills the capacity of the case you will not be able to hear it "shake" around.

Looks like you got a round that was previously chambered then ejected from an AR. I could probably look it up but I wonder what the ballistics of that shape of bullet would be compared to traditional spire FMJ bullets?

Yep. Betcha it's a compressed powder charge.

If the bullet is indeed made of a ligher material, it would make sense.

Lighter bullets in any cartridge typically call for more powder, and a lighter material would be "bulky" for the bullet weight, causing the bullet to be seated deeper on the same dose of powder bypically used for a smaller bullet.

As any handloader knows, some powders call for a compacted load with a typically lead/copper bullet. A bullet of ligher material would intensify this.
