I've seen the number dwindle over the years. I believe that many of the younger shooters see ammo as a disposable, not recyclable. With the cost of 223 ammo prior to our newest shortage who could blame them? Much of what I see now at the range are the one gun wonders. That's all they have or bring to the range. I'll show up with a half a dozen and they show up with one and bring 3x the ammo! There done in half the time packed and gone. With some I see, I believe the safest thing down range is the target!
I've also wondered if this is what others noticed when I first started? If this is nothing more than a weather pattern...
