That very riddle was on Myth busters, I bet that's where your friend saw it, it's true they both land at the same time.

Sorry to be a bit of a smart-ass, but I remember that from physics on High School.
When there are no external forces acting upon two objects falling from the same height regardless of individual weight, both will hit the ground at the same time.
That is to say, if you drop a feather and a stone from the same height with no external forces acting upon it, both the feather and the stone will land on the ground simultaneously because the force of gravity does not change.

This is nothing new. Isaac Newton discovered this relationship a long time ago. Gravity is universal to all matter and is proportional to distance from Earth.
The shot being fired is a perfect example of how to stay in orbit around our planet. Just get your self up beyond the atmosphere (so it won't slow you down due to drag) and travel at, I think it was 18,000 MPH and you'll be able to fall over the side of the earth, thus staying in orbit. Even though gravity is continually trying to pull you down, your "horizontal" speed will make it so that you constantly fall over the edge of Earth.
Slow down a bit and you'll start to fall toward earth - quite quickly.
Someone may have skipped thier science classes in middle school.

Not if you fired the gun straight up.
Sorry, OP neber mentioned the direction of discharge.

so let me get this straight, theoretically, if I drop said bullet from my left hand onto my left foot, and fire said bullet from the gun in my right hand aimed at my right foot, either both will pierce my feet or will not? If they fall at the same rate, which is it, because i will not be trying this experiment out at all. I agree, as long as no external forces are on one of the objects, yes, they would fall at the same rate hitting the ground at the same time.
which bullet will hit the ground first?
