FX FX Impact M3 .22 15.89 JSB Hades tune
- Thread starter Gurugoose
- Start date
I shot those out of my M3 compact pretty much all summer and they were shooting amazing 26 yard groups at 875 FPS. MY settings would be of no use as my compact was misconfigured from FX and my gun was retuned for that heavy valve return spring the FX tech accidentally installed in my gun. I threw my hammer adjustment numbers way off. I do know I has shooting at the stock 150 bar reg 1 and 85 bar reg 2 settings.

Every rifle is different, and we need your barrel length or any mods to really help. My M3 has a standard Superior liner in 500mm and pretty stock internals.
Hammer is set at 16-4
Valve stop full open
1st Reg 120Bar
2nd Reg 95Bar
15.89g Hades go ~995-1005fps depending on the weather

That is a super light pellet for an impact so you will want a really low reg pressure to start. Maybe 85-90 bar. Back the micro adjuster way down and shoot over a chrono slowly working the micro up until the speed flat lines. If this is a desirable speed you are good to go. If not you will either go up on the reg or down depending which way you want the speed to go. When I reach a desired spot I then close the valve adjuster until the speed just decreases a little. That usually helps consistency and efficiency.

I just know you'll need a very low reg pressure.......
I put some in my 600 mm barrel with 2nd reg at 108 and was getting 1055 fps! Way too fast and loud but surprisingly accurate out to 30 yards.

Yeah I also switch to Nielsen 17.5g slugs when the situation calls for it. I use my Impacts for pest control so I want all the performance I can get. It would likely be a tad more accurate if I slowed the pellets down but I dont use my M3 very far with the Hades anyway.

My Impact is a .25, but
I am shooting these 22 15.89gr JSB Hades out of my Leshiy2 @ 835 with a 500mm AP barrel. I could go higher speed but don't want to
