What is a good air gun caliber for hunting iguana’s?

Speed is not accuracy. Speed can make for a flatter trajectory and speed can also destabilize a pellet. You can have a very accurate combination that is quite low velocity with an arcing trajectory to it.

Accuracy comes from stability and consistency. It's a match of barrel type, barrel length, pellet type/shape/weight and velocity. They all need to be in balance for a given pellet. Testing is how you figure out which pellet works best in which combination.

Precision is your ability to apply that accuracy on target.

Could not have said it better!
 
22 Caliber will work but shot placement is the key, I went in February but the only shooting I could get was from a drifting boat and I would only take head shots .
