Barrel changing at JKHAN Noblesse/NXwerks QR bullpup

[anti-squirrel]

My only thought is that you're getting more comfortable with the trigger and the barrel is getting more broken in.  This is the 16mm barrel, right?  From everything I've read, JSB seem to prefer right around 880 or so FPS, and yet here you are will solid proof yours shoots better at higher velocities.  The only thing I can think of is to keep shooting and continue breaking the gun in as an assembly of parts.  IE: don't change a thing- just keep on shooting  

Side note: very interesting (in a good way) seeing how free-floating positively affected accuracy for you.

Thanks,  Yes I need to insure about  long time stability.
What  are yours best   groupings  at 70+ yd from .177 and .22 calibers.

Today I have improved  looking a little bit with using  thermal foam  tube but I am not sure If I not decease  the accuracy.  1/3 pellets are out of MOA

Sorry I have to add  my best grouping also here to let you see which gun it done.
Please let me know which is the easiest way (neck on valve stem   ? )  to reach 985 FPS with 25gr  Monster pellets too  ?

I wanted just insure myself if the Jumbo Heavy accuracy  is still acceptable at 295m/s.


Notice,
Very sorry for my horrible mistake when I used word gays not guys what I was meaning.

Sorry again.

It looks like  that my   "free  floating barrel"  is not long time stable.  The pellets was  sometimes shooting wrong mainly  lower  after some shooting session. 

Therefore I start another project “free floating barrel shroud” .

I centered  shroud to the barrel patiently   and fixed  it at the muzzle by using plastic tube  equipped with rubber O-rig.  A matter of course front shroud band  I have centered and enlarge too.

Just now is shooting  acceptable ( 7 pellets of 10   inside 15mm at 71m - sorry I can not add the picture - Explorrer supress me it add  )   but only time tell me more about of stability.

Sorry I have to praise my gun again .

23 of 30 pellets are inside 1*MOA.

I afraid a little bit to touch the gun for swapping   to the SS valve.
