600 rounds gives a good cushion on what you might need for the course.
The ammo does not get checked (why light load).
There are some strong and weakhand requirements for the course so if the loads are too light you might run into some functioning problems depending on the positions you are shooting from and how tired you are when doing some of the exercises.
If you are handloading for the course, set up for a load around a 130 to 135 PF.
good luck
