Once I went almost a month, but only because it was a new centerfire that showed up a couple days before muzzleloader season and I didn't want to take time off hunting to go to the rifle range.
Usually a new gun comes home, gets optics, gets a trigger job, and goes to the range that same day ... unless it got dark too early, then it's a first thing next morning deal.
Well ... ok, I guess I do have one "virgin" gun. It doesn't have a stock though, just a barreled action. I could shoot it but it might get sorta exciting in a sorta bad way.
