"That is why the method that Gene is using is the only valid way to "index" a barrel for optimum performance. But even at that, will the barrel still suffer from the same tuning maladies that many shooters seem to never solve?

Jackie, all barrels regardless of how they are indexed must still be tuned. The barrel indexing system is completely disassociated with muzzle tuners.

The purpose of barrel indexing is to minimize barrel vibration in the horizontal plane.

The purpose of a muzzle tuner is to control barrel vibration frequency in the vertical plane so as to time bullet exit to coincide with muzzle stop. Yes indeed, the muzzle does stop; at both the top and bottom of its swing as the barrel vibrates.

I feel really dumb here. I just can not understand how you can hang a weight on the end of a barrel and not have the muzzle point down???
