FX FX KING / PANTHERA 600mm .30 JSB 44.75 FPS ?

[Airgun Al]

Anyone have a brand new King or Panthera in .30, 600mm and useing JSB 44.75 pellets?
Im courious what settings, that the FX factory /dealer is shipping them with, right out of the box.
How many fps , right our of the box, using the 44.75 JSB's ?
Does 875 to 900 FPS sound about right ?

Best speed for accuracy for majority of pellets has always been between 800 and 900fps. Most competition shooters shoot right around 860-880fps AFAIK.

If its accurate, and efficient, leave it alone and enjoy!
That seems like a perfect speed for both.

You could up the reg to around 135 bar for slugs however, if you're not familiar with tuning your gun and its shooting pellets accurately I don't recommend messing with it.
