For hunting I am going to nothing but Partitions, solid expanding and bonded core bullet from now on for my 9.3X74R.
I will still shoot dirt clots and rabbits with the Speer 270 gr and the Hornady 286 gr, but for hunting anything bigger then 50 pounds I am not going to use them anymore.

Won't use Swift A-frames because I can't see the value in them at the price they ask. They are excellent, but no better on American game than a solid expanding bullet like a Branes X, and will kill game no better than the Nosler partitions. (They couldn't. All my game shot with Nosler Partitions so far has fallen within a body length) The Noslers I have used in the past in 338, 358 and 375 have all been perfect. In fact I can say the same of the ones I have used in .257" 264" .277" and .308" too. I bet the .366 will be just as good. Very fast kills with full penetration and large wounds.
I can't see how more retained weight is going to help me if I am already getting 100% penetration on everything up to 1500 pounds. So spending the price on Swift A-frames is just foolish for my uses.

I doubt anyone made a better bullet then Swift, but I can't be convinced that they are better than Nosler or Barnes, both of which cost about 60% of what Swift is asking.
