Of the two bullets you mentioned, I'd go Swift. I'm partial to the fact that they took the bonded route, in addition to some other design features that I like.
As others have noted, Swift does have a 286-gr. A-Frame now and Federal is using this bullet in a 9.3 x 62 factory load.
I'd also recommend the 9.3 North Fork in 286. Those would be my very first choice.
