Just got my 338 Edge and it seems to shoot well. I have done some load work-up at 100yds and then at 300yds. Accuracy doesn't really seem to vary greatly between powder charges and seating depths. I am shooting 375 RUM brass, 300 SMK, CCI 250, H1000 (90-93grs), and I seated bullets from a slight jam to .120 off rifling and didn't see much difference between loads. Anyone else find this too? I am overall pretty happy with performance but would like to get the most out of it I can and find a load to settle on so if anyone has suggestions on some tweaking I can do I'd appreciate it.
