Benchmark is on the faster end for shooting lighter weight projectiles in the 85-100gr range, so we normally don't use it much for 120gr and higher.
It can spike on you and it's common to see very tight accuracy nodes when going over max loads.
Approach 27.0gr carefully under 123gr cup and core bullets, using .3gr increments from a start load over a chronograph.
When Bill A. did his initial load testing with 6.5 Grendel, he left Benchmark only for the 90gr TNT and nothing heavier/longer.
Hodgdon's has a lot of data for it for everything from 85gr to 123gr Sierras.
These handbooks are your friends:
