I've re-barrelled countless airguns and firearms for various reasons, more often than not being able to detect the deficiency of the abandoned barrel. Sometimes it is a glaring defect, other times the inadequacy is nearly imperceptible... often mysterious. In MANY cases the barrel is essentially flawless saving a painful oversight, or worse a last minute operation that could have been executed in a better way, or more carefully.
When a barrel is crowned with an piloted champhering tool, that tool must fit well, be free of debris or attributes that marr or otherwise bastardize the lands of the barrel it is trying to perfect.
Case in point;
This .30 Cal 700mm FX "X" barrel has been fired once, and exhibited varying degrees of leading at ONLY four of the five lands in the vicinity of the choke near the muzzle... I'll let you guess which fared better, which fared worse. In my assessment the barrel was crowned with a tool that had a pilot for centering, a VERY common practice utilized in the industry which has inherent perils.
Performing final operations (such as crowning) on barrels is exceedingly more expensive by some techniques than others. The barrel shoots very well. Not as well as it might had it been spared the horrors of having its lands smeared near the crown, which begs the question (in my mind), "How dominant would nearly EVERY X barrel be... if it were just a smidge better built????"
They already impress me ("X" barrels) From what mine tell me (yes I have others), they could be even better, which would be scary good.
Keep doing what you're doing FX... but mind your manners on the finishing details PLEASE !
