If any part of the projectile touches an invulnerable part of the eidolon, then it does no damage. This also seems to apply to guns with multishot, with one projectile hitting the invulnerable part negating the other projectiles that otherwise should have hit. This is based off personal experience though, so you know, sample size of 1. Take it with a grain of salt lol.
