i prefer the swifts on big bovines, elk and smaller is better for barnes territory as my preferred though both will work. i would use on big bovines when i run em hard. when i had the failure with the 50 cal hardcast on the watusi, i went right back to my backpack and grapped the 10" 454 FA83 stoked with those running right at 1800 fps. wouldn't hesitate to use em, but the swifts are a better choice sooooooo unless you're over 1200lbs the barnes are awesome and i imagine we as an industry are missing the boat in the 475 linebaugh and 480 ruger by not using the 275gr xbp. might be the best of the best for anything under 1000lbs outta the 475. don't expect exits, but expect destruction and a quick death.
