Best for what?

accuaracy? Depends on your individual rifle. Personally had good luck with hornady interbonds, and federal premium ballistic tips, winchester ballistic silvertip was OK.

price? Remington corelokts are cheap and are very tough bullets, heard good things about federal fusions too .

shoulder shots? Accubond, interbond, any other bond, corelokts and fusions are strong enough for this too. (NO BALLISTIC TIPS)

rib shots? Ballistic tips are very good at this, anybullet will work though.

flat shooting? I like the hornady light mag 130g interbond for this, only looses 33" at 500 yds.(most are 38-42")
