Chobham effect is where the effective thickness of a plate increases by setting it at an angle to the projectile. Chobham armour was used on tanks, where no plate was set vertically. The article on Chobham armour you found on google probably demonstrated that a plate set at 45 degrees to the projectile was half as thick again as a perpendicular one, thus allowing for lighter armour to be used for the same effect, or increased the effectiveness for the same weight of armour.
So, if the pellet struck a 3 mm thick piece of skull at 45 degrees, the effective thickness of the skull would be greater than a perpendicular strike.
I'm with you, the article was more on the new sorts of materiel, but that makes perfect sense its all about impact v relative to the plane
