Guess it depends on the shroud. Get one from Tony at Talon Tunes, and I'd have to say no. I have a friend that has that setup, and his Condor was doing 980 fps with .22 Kodiaks. No estimate there, that's actual shooting across my Beta Chrony. Got the same results with the shroud off. If you'd like more details, email or PM me direct. Later.
