Here is an example of how to get that last bit of accuracy out of the M3 after you have entered the factory suggested tune parameters. Each caliber and pellet will have a different set of numbers that serve as the "starting point" to tune the gun.
This info is straight from the FX tech department. I followed what they said and my .22 M3 stacks pellets on top of each other at 70 yards. ..18.1gr pellets!
So I had entered the factory tune numbers for 18.1gr w/ a 700mm barrel. They were:
That made my gun shoot 930 feet per second. When I asked AGN how to tune it down to 890fps (pellet's best speed), I was told to "tune it to the curve of the knee".
about a week later the FX tech Melissa told me "Feel free to tune the valve adjuster (front knob) down until you reach the desired velocity. You can turn it until you reach line 4. If you still need to decrease velocity, adjust the Micro wheel down one notch.
.....BAM! I think this technique would aplpy to all calibers and ammo choices. For the recommended tune numbers just email FX USA at [email protected]
Her exact words (James also instructed me on this, hence the "line 4" info.)
Here is the 25.39gr tune for the 700mm Sniper M3 Impact. I will get the tunes for all other pellets and calibers as I film my M3 video series, .22 up to .357.
The first regulator should ALWAYS be set at 150 bar...that is across ALL CALIBERS from .177 to .357. Never shoot an M3 when it is below the front regulator pressure.
Here are default 2nd regulator settings. Happy shooting!
P.S. if you need to know how to properly adjust your M3, here is a 5 minute tuning guide:

The easiest way to slow the speed while maintaining consistency is the valve adjuster knob. Feel free to turn it in until you reach your desired speed.
If you start to notice sporadic speeds every once in a while you may have to back the valve adjuster knob off a little bit turn your hammer spring wheel down 1 notch and then readjust your valve adjuster knob. Just as a heads up in case this occurs you will already know how to address it.
