hey all, im an avid airgunner from across the pond. right now i primarily hunt prairie dogs and jack rabbits in arid scrub land, both are worthy quarry. ive wanted to fiddle with a .20 for a while, i just havent for whatever reason. i am thinking about buying a .20 barrel for one of my falcons in the next few months, if any of you have insight on what kind of energy i could get out of a FAC fn 12 or 19 in .20, as well as rough shot counts, i would appreciate it.

thanks for the great airguns!
todd
