Any accuracy reports on JSB .25 Heavy, impact 700mm Barrel?

Very soon here, I'll be receiving an Impact 700mm tuned to shoot the JSB Heavy 34 grns from Utah airguns. They said it'll be running around 850 FPS. There isn't too much report out there on this set up. I know these pellets have a very good BC, but is it accurate with this set up?

Just got my crown back from FX service center for reg. repair. I asked them to tune it to shoot 34 gr heavies. Test target was one hole five shot groups at 25 yards (their longest range). Here is my five shot group at 50 yards. 860/5 FPS, reg at 150, hammer spring at 5. Have not had a chance to take it out further yet.

My Impact gets the 33g JSB to 880, used it at 70 yesterday and it was very good even though the wind was really howling.
