I usually trim 0.015" below maximum. This is because randomly sampled cases from new bulk brass can be as much as 0.012" under maximum to begin with. By going to 0.015" under maximum, I am sure to have trimmed them all the same length. I will not have to trim again for at least 3 reloads, letting the necks gradually grow back toward maximum.
