That's likely a faulty assumption. Given the number of people that spend far more $$$$$ on a guided hunt and then take a rifle that doesn't work reliably, has poor glass, which they haven't shot nearly enough and that they can't shoot well, I have no problem believing that less than serious people pay for training classes.What we know from comments made by nationally known carbine trainers is that if the have a rifle failure in class it is almost always a home built one. I would assume if the person is taking such a class, they are serious about guns, training and such because those classes are not cheap.
