Here is the Serrano:
New Cricket .25 bullpup.
I shoot 36 shots between fills(filling to 210 bar shooting down to 130 bar).
For the first 3 fills it a tack driver at 105 yards.
Around the 4th fill the POI shifts randomly but usually right or left 2 to 3 inches.
I sight it in AGAIN.
On the next fill the POI shifts randomly but usually right or left 2 to 3 inches AGAIN.
I sight it in AGAIN(now it's almost back to the original settings).
Now it starts all over again and again.
My thoughts:
1. Maybe it's not 'broken in' yet (NOW 1200 pellets thru it). UPDATED.
1a. I shoot at daybreak only when the wind is down.
1c. I have tried cleaning the barrel(between fills) it changed thing a little but no real help.
2. I have tried 3 different 'Known Good' scopes all act the same, it's not the scope.
3. Checked all the screws/bolts I could not find any loose - all tight.
4. Last thought - New Barrel?
5. Send it to a tuner.
Any ideas?
