I've played quite a bit with 7-08's . I just don't think it has enough case capacity for the 168 bullets . I was over loading to where case life was short , accuracy suffered , and if I remember right I was getting less than 2700 FPS with a hot load . I think 2600 is about max velocity with a safe load in a 24"bbl . I could be wrong on these velocities . I am using 140 Berger hunting VLD's with RL17 powder . velocity is good , accuracy is good , and velocity extreme spread is good . the last day I shot it over my chrony my low was 3077 and my high was 3081 for 5 shots . I think RL17 is a very good powder for the 7-08.
I found an old target with some data for the 168 . this would be after I slowed the velocity .
