My new M3 700mm .22

[jcdavis1281]

I am liking my new M3 with 700mm .22 and 580cc bottle (well was 580, just installed 700). Tuned it to shoot cphp at 880fps and 10 mags it took 130 bar, 235 down to 105, that is 280 shots. cphp do great out to about 40 yards but they start to open at 50. Put some 15.89 jsb in without changing anything and 5 shots were touching at 50 so I know it is the cphp not doing as good for that distance. I will play with it more and see if I can get them better, but I am pretty happy with them for $7 per 500.

Reg at 150 first and 100 second
Micro on the 2
Macro on 1
Valve on line 4

Might play with reg later but want to see how it does with the 700mm .177 barrel first.

Ready to see how many shots the 700cc bottle gets. Hopefully that will be tomorrow. It looks nice with 700mm barrel.

Nice rig! Let us know how the 177 barrel performs. My 177 Crown is doing very well.

Congratulations, great gun! That's A LOT of shots! Have fun shooting and tuning it.

I think you need a bigger bottle or longer barrel

I dropped 2nd reg to 80 bar. Something I found interesting was on macro setting 1 fps for 18.13s went up 20-30 and for setting 16 it dropped 40-50. Previous numbers were 770 and 1050 and just changing the 2nd reg from 100 to 80 they went to 800 and 1000.

Currently shooting 18.13s at 770 and using about 10 bar per magazine. That would be 17 mags or 476 shots from 250 to 80 bar. Not as accurate as higher speeds but I think my compressor is going out (would not get above 2800psi yesterday when outside in 55 degree temps, took it inside where it was warmer and it had no problem hitting 3600psi) so I am ok with decent accuracy and high shot count for now.

Below pictures are two groups, left one is 2+ mags and right one is 1 mag. Other picture is about 14 yards behind my target. Wind gusts up to 19mph so that is not really helping the groups.

I am at the in-laws for Thanksgiving, ready to get back home and try my .177 barrel.

@jcdavis1281,
So glad to see someone (you) tuning their .22 DOWN for shot count and accuracy. I have my MKII 700mm 580 setup .177 and am very pleased with shot count and accuracy. Have a 500mm .177 barrel kit on the way to test as well. Great post!
