One place I used to go I was able to shoot slightly downwards into water which would have been well over 100 yards and maybe a lot further, The biggest problem shooting long distances is knowing exactly where your pellet as landed, Hitting a tennis ball at the above distance could be done within a couple if shots, Shooting horizontally however as some many factors, I took a hw100 and a huntsman classic out one morning , Hw 100 was shooting at 11.4 and the huntsman classic was shooting at 10.9 , I was struggling with the hw100 at 60 yards however the huntsman classic would out shoot it, Both were 22 cal,
