Would the triangular shape affect the oscillation of the barrel?
It would seem to me that a round barrel when fired, would oscillate in any number of directions and would be affected by various barrel-to-stock pressures from the 180 degrees of barrel channel. That's why changing pressure points, or allowing the barrel to free float entirely, or adding a Boss modifies the oscillation in a controllable manner.
With a triangular profile, I would guess that oscillation would only happen in one of three directions. If the barrel is bedded or laid in the stock in such a way that two of possible oscillations would be eliminated or reduced(side-to side), then the only probable oscillation would be vertical. Of course, this should show more vertical groupings I would think.
Or it could be just a marketing gimmic.
