Great photo showing good performance:
I've never used Swifts, but was an early - and very satisfied - adopter of the Barnes X -TSX line.
Another bullet that I can rave about, but it is impossible to find these days is the RWS H-Mantle. The performance of that bullet out of my 9.3 X 62 has been down right amazing. From leopard to sable to Cape buffalo, it performed beyond all others. The H-Mantle is not constructed exactly the same as A-Frames or Nosler Partitions. The front end blows up and the rear 70% continues as solid giving exceptional penetration.
Hard to find, and the last time I bought them they were more than a buck a piece. Chump change on a $30k Safari (Ah, the good old days before paying for college tuition, and food, and other foolishness:)
