I have spent a lot of time testing long range shooting with both my .177 Marauder as well as my .22 Condor.
I originally was comparing both Air guns to see which was better at various ranges and have come to the concensus, that will everything taken in consideration, I declare a draw
I find that wind, even a slight breeze < 3 mph can and does have a huge impact on longer ranges. Utilizing Chairgun pro to calculate adjustments, I can successfully take out Starlings at 77 yards with both guns on a still day. From my perspective on a windless day, shots up to 100 yards are possible and anything over that range is out of my zone of comfort. Once you add the element of wind to longer range shooting and a breeze kicks up especially when the wind speed changes frequently, all bets are off as far as consistency is concerned. On those days I feel confident that 50 - 60 yards become the reliable range of long distance shooting.
Having said all that, I am not an expert nor trying to represent myself as one. I am only sharing my own experiences.
