The first cache is a virtual cache to point you to the second cache which is an average sized cache {Ammo box}.
In order to help you a bit with locating the first cache, I will provide this hint - You can be at the same GPS location x 3 , you may find that you need to use the spoiler below to help.

Enjoy!!
