Im sorry but all that about the 177 not getting effected as much by the wind is rubbish, 177 gets blown off by the slightest breeze!
This discussion has been had many many many times before, 177 v 22, longer range vs knockdown power etc
At the end of the day its what you like and what feels right to you, the rifle should be an extension of yourself and likewise the pellet that is fired out.
My prefered calibre is 177, however i do dabble with the .22 and i like it.
Shoot them both and go with what feels right to you, aslong as your happy with it you will be rewarded in the fiel
