I used to shoot a .22 HW77 & Airsporter with a mate who`d a HW90 in .177, he wiped the floor with me every time in the bunny count!
it`s not the calibre, it`s understanding your gun, gauging distances & knowing how to adjust to suit through your scope, Raj`ll give you a lesson, (so will all of the guys above, I`m just winding them up!)
I`ve a near recoiless springer in .177 & one o these days I`m gonna pit it, at daft distances, against my S200 in .22 & post the results on here, good quality ammo is a great help here as well!
knowledge is the key.
