Is there one bullet that does it all in the grendel?

stef1274, stinky coyote, and any others,

What makes the 123 ELDM better than the 120 ELDM in your experience? Have you used it (120ELDM) for game?

Thanks

The consensus is the 123 is easier to develop an accurate load for, some say it was made specifically for the grendel but I don't know.
