I know every gun is different; but, so far, the Hornady Light Magnum ammunition has not been able to deliver its advertised velocity. Itclocks about 50 fps faster than thefastest 30/06 handloads I have been able to safely produce. But not over 2900. I can generally get 3,000 from a 30/06 Ackley Improved; and 3,100 or morefrom a .300 Win Mag. And accuracy, at least for me, has not been very good with the 30/06 Light Mag ammo.
