optimal fps for 34 gr jsb

[milanilo]

hi everyone 

my airgun is fx impact mk2 .25 with power plenum ( pellet liner )

i have been using 34 gr jsb pellets for a long time 

i tuned my fx to shoot them at 840 and i was satisfied so after a while i said why not go higher 

so i tuned to 865 fps and also satisfied  

after that i tuned to 920 fps and also got perfect results 

my question is : have anyone tried higher fps with those pellets and got a good results ?

Hi

What distance are shooting?

I get good results from the MK2s in a Cricket between 925 and 935 at 75 yards which is as far as I can shoot at home. At the same speed, distance and gun I have a little better results from the 34 gr King Heavies with groups averaging just a tad over .50" .

My Impact (gen 1) doesn't like either.

from 30 yards up to 150

In a 22" LW poly they are super accurate at @ 920/930 fps

Also interested in how the heavier pellets do at 1000+ fps.

I'm shooting the 34s at 960 fps. Very accurate so far. Going to try some groups at longer ranges today.

My DS Safari slings em at 954 average on high power. Scary accurate at that speed.

My Uragan was throwing them very accurately at 965
