Yes true Steve,
It takes a lot more knowledge of your combo to make accurate shots at different ranges with a .22 calibre pellet.
Sitting on your zero is fine but making long range shots is where the skill is in with .22 calibre shooting.
I think that's why you get the old rumour that so many believe in that a .177 is more accurate than a .22. This rumour is utter rubbish and both calibres are as accurate as each other.
Where the in- accuracies come in is with the shooter themselves not having the practice and understanding of the ballistics involved to master the calibre.
