Easy "How do you stop shooting...
	Various Steam Achievements...

This achievement appears to be bugged (to our benefit). It unlocks far too soon after the achievement for firing 100,000 shots. I got it after firing only a little over 101,000 shots.

Complete the indicated task to unlock the achievement.
