Eppie, how much does a bullet's coriolis effect influence its trajectory if the twist goes from 1:12 to 1:11, or 1:11 to 1:10 for a given 30 caliber bullet leaving at a given muzzle velocity? MOA units at any range are fine to describe the change.

I ask because I've shot .308 Win's with 190's at 1000 yards from 1:12, 1:11 and 1:10 twist barrels with no difference in accuracy.
