Fx Impact on chrony today

Did some shooting results

33.95 jsb King heavy Fx impact power 4 low 823 high 846 average 830 spread 23 Power 5 low 842 high 853 average 848 spread 10.28 Power high low 853 high 862 average 858 spread 8.95 Valve in front on 4. 
Looks like high power was most stable every thing maxed out front on 4 power max thought I would get a little higher velocity with this set up. 
Regulator is showing 145ish close to 150 have not adjusted it at all. Guessing it is more like 140 as that is what they are set on and it was resealed and set at AOA when I sent it in. 

Any thoughts or comparisons. Think in Ted's video he said he was shooting the 25 on 4 around 860fps. 

Love the rifle really nice.

"sniperlabyo".... but don't alway shoot the best accuracy,


Hi Ernest

What is the reason for this? It has low FPS spread no doubt, and uses the same ST barrel as other FX models.

Noticed you've also gotten rid of the extendable shroud for a fixed one.
at a certain point the pellet become unstable at a given speed and all barrel has it's limitation even a smooth twist at the same caliber.
The FX stackable are so much quieter than the extendable so I got another on my .25 smooth twist standard cricket --she setup to shoot the 34g at 900fps
