For my particular rifle, the 168s were very fussy and difficult to get shooting with the 215s. Messed with seating depth a lot to tune them and even then I wasnt fully satisfied. When I tried the 210s it just didn’t matter how they were seated, they all just started shooting great. I havent looked at details on SD etc but I imagine they were better too. For me it was just a night and day difference with accuracy.
