[Harry Potter] How effective would a gun be against wizards?

Is the protego spell strong enough to block bullets or not?

We never see it but considering what other shit protego has stopped it could certainly stop bullets.

But that doesn't matter because a gun would take out a wizard much faster then almost any wizard could cast a spell to either defend or attack.
