Slight point of order, but the relationship between energy and velocity isn't linear, so actually the .177 pellet at half the weight is actually only travelling approx 1.4 times as fast for the same energy (square root of 2). However they do seem slightly less sensitive to wind in my experience.There is no contest on calibre IMHO, it has to be .177! It is strange though that about 80% of air rifles sold are .22, but this is undoubtedly because people naturally assume that bigger is more powerful which is a farce in the case of air weapons restricted to 12 ft/lbs. The laws of physics would suggest that a .177 pellet or around 10 grains will have to be travelling around twice as fast as a .22 pellet of around 20 grains. People always think that a .22 pellet is affected less by wind too, but a .177 pellet gets there quicker and therefore has less time to be affected by the wind!
It is no coincidence that most professional vermin controllers choose the .177.
You should also consider a 'Gas Ram' though over a springer where you are compressing air rather than a spring. Still quite heavy, but you get the best of both worlds!

I'd look at gas-rams (plenty of choice now that he technology isn't ring-fenced by patent any longer.)
I've used and like gas ram guns, and know more people are making them (Crosman, Hatsan, etc.) but does anyone make a good one?
