Yes, TAC is good.
Start at 27.0gr under a 120gr class cup and core bullet, work up in .3gr increments over a chronograph until 28.8gr max load. Make sure you dont have any excursions from the trend line.
Alexander Arms had a lot of data with TAC in that weight class with 28.8gr being the max under the 120gr Nosler Ballistic Tip, 120gr SMK, and 120gr Norma FMJ. 28.5gr was the max under the Berger 120gr Match, so take that into consideration with the ELD-M.
In Volume II, the max listed load is 28.5gr of TAC under the 123gr A-MAX (ELD-M replaced the A-MAX with a new tip).
Lots of data for it in Hornadys manuals, as well as Sierra.
Sierras data in interesting because it lists 28.8gr max for their 120gr bullets, but 28.9gr max for the 123gr SMK.
We have a bunch of load data in the Grendel Handbooks for TAC:
