Yeah, but that's complete bullcrap and instill and builds up a false-confidence in people. They think, "Well, 600 was easy, so I bet I can go shoot 1,000 next time!"
This will only produce yuppies who still don't know how to do anything for themselves. They don't REALLY know how to shoot, they don't have a clue how to build precision ammo, no idea how to build a drop chart, or determine their drops, and they still don't know anything about their weapon/weapons other than what little bit they were taught at the class.
Other than my opinions on it, if someone's got the money, go for it.
