Every time Dave clocks in, he tells me, there are people there, shooting. Even during this last cold snap, when we had highs below zero for about a week, there would be a dozen people at the range banging away, he reports. Often, shooting is all they’re doing. Not shooting at anything, just shooting. That’s the part I don’t understand. The other day, Dave said, two men showed up in a Mercedes, parked, and left it running for two hours while they shot. They would burn through 30-round magazines in their ARs as fast they could, warm their hands over the ventilated handguard, and then reload and shoot some more. At nothing. Not once in two hours did they go downrange to set up a target.
