[QUOTE="Bart B, post: 551208, member: 5302"] There's more bullet yaw (tip moving in a circle about the trajectory axis) caused by slight unbalance of the bullet than making its point perfect. Over 90% of all bullets are unbalanced by some degree. The yaw caused by unbalance makes small changes in drag, or bullet coefficient. Although it's typically 2% or less with Sierra's best match bullets, the difference in vertical shot displacement caused by this is significant. Do you know how much it is compared to a muzzle velocity spread of 20 fps or a standard deviation of 7 fps? [/QUOTE]
