This phenomenon happens a lot, as anybody who's spent a moment examining the walls, ceiling, and floor of a public range could tell you.
This isn't strange at all, at least according to a theory I first heard from Shootin' Buddy. Think about pretty much every internet firearms forum you’ve seen:
Sure, the posts may start differently:
“I pulled out my (rare and expensive) pre-ban HK91 with ACOG/suppressed Mk.23…”
“I fired my (loud and fiery) Mosin M44/2″ .357 stoked with handloads…”
“I shot that (amazingly skillful) .25″ group/6 second El Pres…”
But they all end the same:
“…and everyone was looking at me.”
As best I can tell from reading the internets, the main reason for owning and shooting firearms is to receive the silent adulation of strangers at the range.
