About six times further with zero drag. So 3.6Km, or from Buckingham Palace to St Paul's Cathedral.

That's already what zero drag meant

on Earth or on the Moon tho?
Have you ever tried to run on the moon? Bloody difficult.

There are a few guns that exist that could achieve the necessary velocity (just shy of 4,000 mph) but they’re not handheld. But yes, it would be possible for the right gun to fire a bullet that went around the moon and hit you in the back of the head.
