Perhaps it's not about being "a serious shooter".
Maybe for these people, it's about being able to hit
a man sized target at acceptable self-defense ranges.
Not everyone is an IDPA geek, or a hard-core reloader
or a bullseye expert. Maybe they just go to the range
ocassionally to make sure thier peice still works, and
that they can still "hit the broad side of a barn".
Not everyone is a gun nut, after all.
