I need to sight in my 7MM Rem Mag. I am going on an elk hunt next fall and plan on using 160 grain, Accubond, Winchester CT rounds. These rounds are rather expensive. Can I get away with sighting in with a less expensive 160 grain rounds with the same muzzle velocity and then fine tune with a couple of the Accubond rounds? I have not shot my rifle in a few years and it has been moved twice. I am thinking it may take more than a few rounds to sight it in.
Thanks for the help.
