The sizes you have are just fine. Feed them off smallest to largest. In the wild if a 65 gram rat walked in front of a 336 gram snake it wouldn't hesitate to kill it and eat it. It might wait a while longer before taking it's next meal. The 15% figure is just a gauge/guideline to use but not an absolute.
In the wild they don't bury a scale in the ground and watch for the right sized prey to cross over before striking.
