The 22 in reality probably nearly replicates the trajectory with same same pellets.......
BUT, I too enjoyed an R9 20, and preferred it over 17 and 20. The Crosman Premier 14.3 - believe it's the same or about a copy of the JSB, is about all your really need, but I did get some great accuracy with Beeman Crow Mag. The 14.3s did about 675 or so mv, and flattened tree squirrels like a hammer, around 60-70 yds when I connected.
All work when you place a shot, but if you fall below say 600-650 mv for any, they drop fast. Enjoy your 20 R9.
