I have a good pile of this ammo for both my 30-06 and my 270. The 30-06 is the old Light mag ammo and, the 270 is the Superformance ammo. I shot both rifles and chrony'd them. The 30-06 was shooting the 165 gr SST. and 270 was the 130 gr SST. The 270 clocked in right at advertised speed. the 30-06 actually clocked above what they advertised, (3025 ave). Has anyone shot this ammo much and what is your experience with it's actual velocities? FYI, the 30-06 shoots a 1" group at 100 yards out of a custom 24" barrel, The .270 shoots under 1/2 out of a custom 24" barrel. Thanks for your imput.
