Disappointing results.... It is possible that with their lower velocity (compared to the lighter JSBs) the barrel is at a different point in its vibration cycle.... If so, it could benefit from a barrel band or a tuning weight.... if such is practical on your gun....Bob
It could be a mismatch between bullet and liner.... You're pretty much the guinea pig here.... *grin*....Bob
Not sure but from all the reading of geek posts would a CF sleeve epoxied to the barrel as a stiffener aid in taming the barrel harmonics and whipping
The silhuette season is over so it's time to see if more power can be had from the gun. In preparation for that I beefed up the rear of the breech. M4 threaded holes were done by the factory so this implies that the original design of this gun had a supporting bar for the cylinder where the sidelever lever holding screw attaches.I would actually recommend this mod for all 9mm Evanix owners, takes few minutes to make and beefes up the breech end considerably.
