Partitions are and continue to be the standard. If your rifle shoots them, use them! I used them in Africa out of my 300 Weatherby with great results. That said the locus of this thread included Sierras, which I would never use on anything except varmints at any speed in any caliber.
I have no problem sending Sierra bullets at elk with 7-08. My freezer has been filled several times over using them. Experience trumps guessing.
