They are about like small computer store owners. Hey, I like (guns/computers) wouldn't it be great to...
Unfortunately, they often lack basic social skills and business skills. I've had two computer shop guys that were one stop -- never again experiences when they make you feel like an ****** the first question out of your mouth. As someone who's only "new" computer was bought in 1988, I was hardly asking about where to find the "any" key. Either that our they are just too busy to acknowledge your presence.
Gun dealers are not quite as bad, in my experience, but their prices often lack any basis in reality and their "gun knowledge" and openly expressed worldviews can lead to a lot of mental notes to just keep your mouth shut and nod.
Did find a good gunshop in the area recently though. It has 1937/1940 Indian .303, clean in the original string-tied paper packets. Bought 1000 rounds and I'm going to try it out this weekend if I can. If it's good, then time for another 1000 or so ($110/1000)
