Over decades I have tested about every .22 18 Gr Diablo pellet available and never found a pellet that would hang with the Air Arms pellets in terms of accuracy and consistency (except perhaps the H&N Baracuda Match 21.14 Gr) until recently. In several of my .22s, the JTS 18s will hang right with the AA pellets, if not perform better. Below is an example. I have shot tens of thousands of AA pellets and admittedly probably less than 500 of the JTS pellets, but the outcome has been very promising.
The groups below were shot using my .22 Cricket Long incorporating the Georgia Airguns Charlie Frear power tune at 50 yards.
