Air powered arrow launchers are a lot of fun, but will never be considered archery by many States, nor should they be.
After playing with them for more than a few years I understand that the power these things are capable of has a few limits, mostly the amount of air pressure available, and the amount of air you can get the valve to flow without dumping everything in the tank.
The niche that I think these things should be geared toward is wild hog hunting. We only have a few truly wild hogs here in Ohio, but these hogs have practically overrun large areas of Texas, Florida and other states, and if someone geared these air rifles toward hog hunting the sales would skyrocket. I think if set up right, they would have huge advantages over both firearms and archery gear, including the most powerful crossbows.
The advantages are:
1. They are not firearms according to the ATF, and most States, so they could potentially be used in areas where hogs are abundant, but firearms are prohibited.
2. The power level is easily varied in many air rifles with the simple turn of a screw, and with over 3,000 psi on tap, you can use as much or as little as you need.
3. Because they are not a firearm, they can be equipped with sound moderators as long as it is made as part of the frame and this would bring the sound level down below that of a rimfire rifle.
4. With the power available, a good stout broad head could be driven through the largest hog.
The disadvantages of the present crop of air powered arrow launchers are:
1. They use massive amounts of the available air, and as BigbirdVa can tell you, NOBODY looks forward to using a Hill hand pump for 30 minutesto pressurize the tank and only get a few shots.
2. A good portion of that air is wasted inside the hollow barrel and arrow tube bringing it up to pressure before the arrow starts to move forward off the barrel. A better idea would be a dart type of internal projectile with fletching at the rear with a sabot to provide a seal, and a folding broad head at the front that would fit inside the barrel. Everything loaded from the breech just like a standard air rifle.
3. I'm convinced that if you really want an arrow traveling 600-800 FPS, these are more than capable of it. Some guys are producing pressure vessels and valves that use 4,000 to 5,000 psi, not the normal 3,000 psi like the Benjamin. There are several guys that have already launched arrows/darts from large bore air rifles (50-70 cal), and easily achieved 600 FPS. Problem is the fletching and broad heads are not up to the task of those speeds, and something like the FOB may be the way forward.
Not to take away from crossbows, but I think on this one area, air bows or whatever you want to call them could become the hog hunting tool of choice.
