Pat, not only have I been inside a gun shoppe oncet, but I've read a couple of gun articles (you know--imaginary goats or 9 vs. 45 with mandatory photos of pointing firearms at self) written by Kalifornee guys in flowered shirts who also write about "hot rods" and beach volleyball. Does this make me double-certified expert?
444, Pat knows a lot more, but as another alternative, have you tried Kellube on your carbine? I like it for when you shoot a lot.
Hey, don't worry it's only money (I tell the IRS and the IDoR this all the time). On the positive side, think of all the antinquing you'll not have to do by enrolling in class. "Honey, I'd love to go look at old, feckless furniture, but I've GOT to get ready for Gunsite."
