Very nice!

Was yours set at 150bar from factory?

Mine was set at 150 and I haven’t messed with it yet. I’ve been shooting the 380mm . I have 34gr on the way to try in the 700mm.

what’s your power wheel at? How fast can you shoot the 34grs?

I’ve been testing the 25.4’s stock settings PW Max they come out at 855-860. They’ve been shooting best on PW4 at 840-845. On Max it sounds like I’m wasting air. Thinking maybe I’m reaching the max velocity for the 380mm.

I’m limited to 75yds at the moment but the short barrel is shooting well. I can shoot pretty consistent .75-.625 groups, some are 1” which I consider crappy. Shot my best 5 shot this evening in 0 wind.

I got a 22 and it was at 130bar factory. I tuned the hammer, ported the barrel inlet, and valve seat. Currently 18.13 JSBs at 920 fps on 380mm barrel. Porting did a lot. Hammer is turned way down, this gun is QUIET. But I'm also shooting 30gr at 920 fps on 700mm. I turned it up 1 bar 😂 131 is where it likes to be for now. Makes me wonder if yall have heavier hammers.... 🤔
 
“Orange Crush”.

Sorry but I’m actually a long time Packer Fan that hasn’t gotten over SB 32.

I like to shoot the helmet out of spite 😁

love the look of your yellow jacket.

Long-gun-Dallas. Do you have any pics of the porting you did. What kind of gains over stock power.

I ran some 25.4gr JSB’s down the 700mm barrel and on Max they were going almost 1,000 fps. I expect the 34gr to go about 900-920. Not sure I’ll need much more power than that for slugs but I’d love for you to elaborate on your porting experience.

Hard to take a pic of the port on the inside of the barrel, but it was elongated and radiused towards the back of where the pellet would sit. There's basically a 90degree angle there, and you want to turn it down and radius it. Huge gains in doing that alone. 

Probe was ported to match. Venturi on opening sized to match 25/30 cal setting on port wheel. 75fps gain on 700mm 60fps on 380. Though, I didn't get as aggressive with porting on the shorter barrel.

Factory max the jsb 18.13s were doing 1090 in 700mm 950 on 380mm after port work. Still at 130 bar
