Ok, I see that now, for shooting east and west.
The target would be rotating slower than you if you were shooting north or south away from the equator and faster if you were shooting toward the equator and that would be the true coriolis effect. I may sit down later and try to calculate that distance.
After a google search, at the latitude of Camp Pendleton, the Coriolis affect would move the bullet about 3 inches laterally at 1000 yards.
