I have a 25 Bully.
My it tooks some time until i had good results with it.
It was not like my at44 out of the box that i adjust with 2 magazins of pellets and than have fun.
I tooks more time to find the right shoot technik on table sticks or wathever, i dont use a bipod.
Since the barrel and the scope are relativly far apart and can be edged by wrong shoot technik
Besides the hs screw has to be on very light possition and the workingpressure between 180-120bar
With this settings the Bully gives me 20 accurate shots.
I have 5000 + with this gun
I would prepare if i hade the choice to buy a Slayer ,sam yang,or condor
Have more power in 9mm and are as i think more mellow
