Reply to comment by The_Illist_Physicist in Does the spinning of a bullet have any effect on its drag? by Eastern-Ability8411

Just to clarify, is that additional drag in the direction of travel? Or is it the same amount in the direction of travel plus a small lateral amount in the direction of spin?

Excellent point. The latter. If you divide the motion of the bullet into a linear component and a rotational component, the additional friction drag only acts against the rotation. So the spinning bullet will slow its rotation over time, but the two bullets should have almost exactly the same speed.
