My 7mm RM likes:
150 Nosler Partitions
162 grain Hornady SP
Both ABLR

If I had to have just one bullet, it would be a tough choice.
For Antelope Mt. Goat, Sheep I’d pick ABLR or Horn 162 grain SP
For deer 162 Horn SP
For elk, moose or deer 150 grain Partitions

These all shoot sub MOA. But for some reason those Hornady 162 Interlock are crazy accurate in my 7mm RM.

I prefer classic.
