Some General Int. Help

So, I am back into Arduino Programming, and I am building an Airsoft Sentry Gun. Can I have an Int that is for bullet count, instead of a Pin Number?

So, like, would: int bulletCount = 500
in the startup mess up the code?
I have Serial set up at 9600ps and I want it to print the approximate amount, so it wont fire dry.

Thanks in advance!

JUST AS A NOTE, I AM USING THE Arduino UNO.

No, 500 in an int won't screw anything up, though the lack of semicolon might.
