I have never obseved the correlation of barrel twist and the "optimum" bullet weight for that twist in test firing. I have never shot a statistically significant number of different twist barrels in test fixtures to claim there is NO difference but I have shot enough to say any difference is less than the combination of my shooting skills and barrel to barrel accuracy differences.
Also the bullet not tracking the trajectory theroy has never been observed in rifle trajectories that I know of. It comes from artillery or mortars where the projectile has to make a VERY sharp turn at the top of a VERY steep trajectory.
