They have airguns that shoot at 1,600fps now, and with Gamo's new pellet, you can kill wild boar, deer, etc with a headshot.
Pellets are inherently unstable over 1100 fps. Once they pass the speed of sound, they tumble, and due to their light weight, will go off course. Most
of the higher velocities cited on manufacturers goods are produced by useing very lightweight alloy pellets instead of lead.
I have an air rifle here that will go 1200fps with alloy pellets, and trust me, you wouldn't anything over 30 yards with it, never mind a precision
death shot. If I use sub-sonic lead pellets, I can get good, consistent grouping WITH GOOD pellets. Cheaper pellets give a much larger grouping. Some
are almost as bad as the alloy pellets (GAMO, anyone?).
Windage and distance are huge factors with pellets.
.22 is better than .177 for hunting, but the increased weight gives reduced velocity. Usually with air rifles, you are looking at accuracy as opposed
to kinetic delivery to kill a quarry. From my experience, hollow point and round heads seem to be more accurate that pointed pellets or flat heads.
A good air rifle, or even over 360fps air pistol will bag you a lot of edibles.
An air rifle could be used as a defensive weapon if you can aim to the face or throat.
Cheap or old air rifles can be re-sprung, if you have a business nearby that uses hydrolic compressin machinery. You can buy excelelnt springs as
replacements. The problem is compressing them into the rifle. Pistol springs can also be replaced, but their tollerances are much less than air
rifles.
Pheasibly, you could probablt get 2000-3000 fps out of a rifle. You are probably looking at up to 100lbs of pressure to cock it, though, and accuracy
wouldn't be anything to write home about, but as a defensive against large creatures and people, it would produce excellent results at close to mid
quarters. Again, spring swapping would eventually give rise to fatigue in the metals.
I would also figure that some sort of toxin or poison could administered via a hollow point pellet, as the resistance from the air would keep it in
place. I really don't know about toxins or poisons, but it's a thought. Snake poison, perhaps? Would be very usefull against larger game. Not very
practical though. And you'd have to track it. More than likely you would have to track any large game shot with a pellet. More than likely, you would
need multiple shots, anyway.
FYI, supersonic (over 1100fps) pellets make a lot more noise than sub-sonic. Something to consider when hunting scitterish 'meals'.
