Big shout out to BRG. I shot this today at 100 yards with JSB 34MKII's 905fps 120bar PL1 after his master tune. You can tell by the trajectory it's at yardage. We know each other so he knows my guns and shooting style. After his repair and tune, a 5 shot tweek to scope? I made this first shot!! It is a different gun now. The action is more robust, precise. obviously his barrel prep is outstanding If you want a great mechanic This man is it. He will take you through a process, your included in all the way. Pics, texts, whatever it takes to get your gun right. You need to know what you want from the gun.I got MORE!
