Sniping iguana in south Florida. Iguana burrow and munch on landscaping. In cold weather they fall out of trees into traffic and on to pedestrians.
I bet they taste like chicken.
Iguana Solutions has a boat-load of videos. Some with snare poles. Others with airguns.
Her airgun deserves comment. It fires a .22 caliber, 25 grain pellet at about 850 fps. It uses a tank of pre-compressed air so she can get multiple shots. She really lays them out with head-shots. It is not cheap at $1400 but it is a tool they use every day.
|About fifty shots from a fully charged tank before the shooter starts to see velocity fall.|
One concern with a weapon that uses a precharged tank is that velocity is likely to fall-off as the pressure in the tank falls.
One work-around is to use a regulator to control the pressure ported to the pellet. Obviously, the regulated pressure must be less than the pressure in the tank. Regulators cannot create energy!
That presents the designer with a dilemma. If he chooses a lower pressure to extend the plateau then he loses power. If he chooses higher pressure to maximize power than he shortens the number of shots available to the shooter before trajectories become unpredictable.
Air rifles work for Iguana Solutions because there is no brass to police and they are quieter than .22s, even though there are many low-noise .22 rounds available. Those options include CB, and CCI "Quiet" .22LR and even the humble .22 Short.
