I need help tuning FX Impact M3 .22 cal . I had 250 bar on regulator and shot 25-30 H&N 18 and used down to 210 bar off the 250 charge. I would like to get a more efficient use from my 300 cc compact 500mm, I'm shooting 851 fps +- with H&N 18(18.13) Reg #1 150 bar,Reg #2 pressure gauge 75.The micro set @2,Macro 16 fronyt valve looks like 5.5-6 turns. This was set at factory with no adjustments. Any tuning help would be greatly appreciated .

not sure if you checked here https://www.airgunnation.com/topic/your-m3-tunes-here/ but if not here or you don't get any responses I would give FX a call on their stock tune...

That "tune" is just their neglect to actually tune the gun. As long as fx keeps getting paid, it seems they care less and less.
As for tune, you'll have to play with the controls and see what works. I'd drop the regulator to 130bar first. Then play with the front valve adjuster next. Finally dial in your hammer. Plenty of YouTube videos if you have performance issues after all that.

My M3 Compact .22 only gets around 60 shots shooting JSB 18.13gr pellets at 890fps.
That small bottle just doesn't have enough to shoot much more.

Larry, I’m confused! You stated, you shoot From 250 to 210 and got 25-30 shoots. And your 1st regulator is set at 150 bar and your 2nd regulator is set at 75 bar. If you don’t shoot from a full fill to the second regulator setting. How would know how many shoots your getting per fill. IMHO, I’d guess it has a putty good tune, if your getting 851fps with slugs. With a 75 bar regulator set point. May I suggest a full shoot string. If anything might be wrong with your gun. It might sound Blurpee. I find I prefer a sharper cleaner sound that comes from a regular set point being higher. But that doesn’t always mean that best for accuracy.

Try Ted's Holdover on YouTube. He's an interesting guy. Always clear and concise in his videos with out the babbling most youtubers feel is obligatory. He has been air gunning a long time and is familiar with MK1, II and the M3 Impacts and Wildcats. He is totally honest in his content and if he says it, you can believe it's true.
