Favorite Crown 600mm .22 18.13 Pellet Settings Please

[Bodacious]

Hoping to find information regarding setting up my new FX Crown .22cal 600mm for JSB 18.13 pellets.
My new delivered settings are:
90bar:
3 position wheel on HIGH
PW ( 1-23 click options) set at 23 or Max
880 fps

Thanks

Looks like you have it right where it needs to be

Clean the barrel and shoot it. That's a good tune.

At the present tune it shoots 18.13 ragged hole at 50 yards 880fps. If I take it out to 80 yards the group opens up to 1.5" plus.
If i shoot 15.89's at that same HIGH setting the chrony goes up to 945 and the 15.89 group in at under 1/2".
I was thinking if I should increase the FPS on the 18's up to 930-940 for similar results?
The 16's are as tight as the 18's at 50 yards.

You need to do more reading. Results from one pellet to the next do not transfer, except for velocity. No one can tell you what one pellet is going to do in your gun. There’s no short cut. Do the work and start testing on your own.
