How do I get info on my shell?

I have a brass bullet and im trying to find information on it where do I find it and how do I identify it?

The best thing to do would be to post a photo right here in the forum, and there are instructions on that found here:

In lieu of a photo, you could just give the best written description that you can with colors, shapes, headstamp, and all pertinent characteristics and detailed measurements that you can give.
Somebody here will probably know what it is.

When you say “brass bullet” do you mean that the projectile is brass, as in solid brass, or just brass-colored looking? Is it round nose full metal jacket, truncated, or hollow point, etc…
