WOW! Impressive! But I suspect accuracy will be bad with pellets beyond 50 yards. I get much better accuracy with my Condor at even greater velocity (1050 fps) with Rat Sniper Hollowpoint slugs (37 gr. swaged), while pellets flew dangerously out of control past 50 yards.
I'd be interested to see your groups with these JSB pellets at this power level at 50 and 100 meters.
From what I can see in the videos (without any written description), it looks like a fine conversion for the Condor.
As for the moderator, mine (TalonTunes) seems much quieter, although it's difficult to tell in a video.
