i can only chime in for the 308win

i have shot 150gr. - 165gr. ( that is all i need for deer in maine ) in several differant guns chabered in the 308win.

i have come down to find that the federal premium or ( vital shok ) 150gr. nosler ballistic tips shots the best at 100yds . ( under an 1" ) now for hunting ( just in case i come across a bear during the deer/bear season )i have found that the winchester power points got roughly 2" and the best was federal vital shok 165gr. sierra gameking's soft point boattail.

also works great for shots under 50yds. best initial damage i have seen in many ammo i have used for deer.
