If these barrels deliver what the people in the know claim, then they will be the holy grail for FT shooters. There's not that much improvement available in pure group size from a good barrel and with good pellets. But if a barrel could deliver that level of accuracy, reduce the need to seek out specific batches of pellets, reduce the need to clean, and all that together with a potential improvement in wind performance from the better BC I can see the tubes (and rifles fitted with them) changing hands for considerable sums.
