This is just my opinion, take it for what it's worth? I think a lot of it has to do with the ethics of hunting. The economy has a lot to do with it also, but if the demand is there they probably would still be making them. With the ethics of hunting going back to more of the old style way of hunting, the demand isn't there that once was. If you think back, a few years ago everbody wanted 3-1/2" shells and now it's going back to more wanting a 3" shell, the same with decoys, blinds, camo, calls. A few years ago if you couldn't shoot a bird at 50+ yards you needed something different, now people are starting to look at keeping it more of a sport, and getting birds in closer 30-35 yards as a long shot, if you can't get that bird in closer then the bird wins and lives a day longer? A lot of old hunters wouldn't think of taking a bird beyond 40 yards, but with todays technologies and equipment taking a bird at 55-60 yards was much of a problem. I think hunters are starting to put more sport back into the sport of hunting? Again just my opinion take it what it's worth, I'm just an old style hunter that enjoys the sport of hunting.
