they are MORE expensive to produce than standard barrels, the special 'blanks' (in fact specialist tubing) costs nearly as much as a LW rifled blank (ie. the unworked FX balnks cost nearly as much as the worked LW blanks).

One aspect of the SmoothTwist barrels is their seeming immunity to fouling & they dont cut the pellet resulting in a more uniform projectile.

The guy who made the video is in the States and shoots at FAC levels, he's had an Edgun for a while - they are often messed with to get max power, that could well be his problem here. Most American air gun users select pellets on a weight basis (for some reason ) I've tried to educate them about head sizes etc. but they tell me the makers dont provide the information, well that could also be an issue with his LW barrelled Edgun.

FX will not be making SmoothTwist barrels available to the public.
