my recent guns and ammo magazione published some data in chart form on the bottom of page 66(for those of you that get the magazine).
It show the 30-06 with federal 165gr TB, and hornady 165gr SST out performing the the 300winmag's winchester 165gr FS.
now i think somebody going to have an opinion about this.
dont just look at 100 yards either look downrange. now that retention probably has to do with bullet design but... i havve to go to class soon but if there are requests i might post the data later
