And there is less chance of it drifting over, say on a hot day.
When I used to use 7.9 Premiers that's all I had mine set to. It was always a smoother reaction compared to 815-820fps. Also the accuracy was better, not sure why but the groups were on average about 40% tighter at the lower speed.

Even my current 8.4s JSB pellets run at 770fps it gives a nice smooth response. Gives me plenty of space for themperature changes, last year the chrono readings and mine (using the cb625) where only a few fps different at 4 of the events.
