Most, but not all, rabbit head shots with my .20 using FTT's the pellet can be felt just under the skin or imbedded in the skull exit side (sorry that was gsxrman not you)

And while .177 may be "flatter" shooting it is not "flat", it still has (according to chairgun) about 1.5" drop at 45yds (using my set up parameters), .20 is 2.75" so any shooter that can adjust for one can adjust for the other

But yes accuracy is king & both my .20's are superbly accurate.
Mr Bear, my drop at 45 is 0.66" and 1.44" at 50 using same program.
So, a lot flatter than most think and superb in a breeze.
The issue is determining the distance, so something looks to be 45 but is actually 48 or 41 then your POI changes massively where as mine hardly moves.
That is the real advantage of the calibre and still penetrates the full brains and eyes at that range. Words used are "easier" or "more forgiving" but at the end of the day the .177 hits the mark more often than the other calibres on a course or out in the field, unless its pre determined fixed range like the silhouettes are set to 20,30,36 and 45 and all standing shots then larger calibres stand a chance but dont punch as tight a group as .177 therefore the calibre exists to be the best at sub 12.
