I have not been able to find an definitive answer to this question, and the answer probably depends on how the rifle is being used (e.g., general hunting, casual target shooting, competition shooting, etc.). It probably is also dependent on whether one crimps the bullets or not. But, if one has a batch of brass and ALL OF IT is shorter than maximum, what amount of case length deviation in the batch (in thousandths of an inch) would prompt you to trim the brass? Would you consider this a constant number regardless of the cartridge, or could a longer cartridge like 30-06 tolerate more case length variation in the batch than a short cartridge like the 22 Hornet?
