Newb question about head stamp

[Snipper33]

I'm just now getting into reloading, and have 500+ pieces of brass with this head stamp. Can anyone tell me anything about this brass? Is it worth starting load development with these, or should I trash them and buy something else?

Good resource to keep around. These are American ballistics co. Never heard of them before, but they should be fine for plinking loads. If you are looking for ultimate precision, sell them for something better. As always, start low and work up.
