I seem to remember hearing that the form used to have a ton of stuff listed as options; target shooting, hunting, personal protection, etc. And if you wrote anything but "protection" or "all proper purposes," the license would get turned down, since apparently those are the only reasons for which licenses are issued. Well, now they just flat out tell you the "correct" answers. As long as you put either on the form, it shouldn't matter. They don't write the purpose on the license itself.
