Good comments! I hope y'all don't mind my 2 cents. Here's something completely different...
I hunt big game exclusively with Nosler Partitions. Swift, Barnes, and other super-premium bullets are all very good, but not noticeably different from Noslers in the field, at much higher cost. Nosler 130 grain .270s and 200 grain .30's in my 300 Win Mag both shoot around 1" groups, so I've not done much hunting with other brands like Hornady spire-points or Sierras. I don't mess with success.
For accuracy, my .270 shoots 130 grain Speer Boat-tails and the original Nosler solid base boat-tail in mind-bendingly small groups. A 1000-yard benchrester once told me that inside 300 yards, Nosler Ballistic Tips will show you 95% of your rifle's ultimate accuracy, for much less cost than match bullets. Can't say that I disagree with that. (FWIW, boat-tails all cause too much meat damage for me to hunt with.)
I have nothing against Sierra (I want to try the 90 grain hollow points suggested here) or Hornady (I have some 180 and 190 grains to re-try in my .300). I just haven't found a compelling reason to switch from my current loads that have worked for so many years.
