So I just purchased my first 7x57 (M70 SG Lightweight), and am pondering loads. My first inclination was to go 140’s since the load data suggests similar charges as the 7mm-08. I understand that the 7x57 has more case capacity and load data is light in respect to older rifles.

While doing some forum reading it seems most 7x57 guru’s prefer bullets in the 160-175 grain class. Is this because of nostalgia? or because most are built on a long action, so since there’s room, might as well use it?
