Almost all the game I have taken with the 9.3 has been using the Norma Dual-Core 286 gr bullet. Used it for years and have put quite a few tons, literally, of moose caribou and bear in the freezer using it. The largest moose I ever took was with the old Kynoch 286 gr RN that was designed for the British 360 No 2 cartridge. It is a big bluff-nosed soft point with a mild steel jacket, and really piles game up in a hurry, as does the Norma.
This is the first animal I have used the Speer bullet on. After seeing what it did to this bear, and River Rat's moose, my feeling is that if we only had it to use for big game, it would be enough.
I have a handful of the 286 Privi-Partisan bullets that a friend gave me to try, but have not used them yet. The Hornady bullet looks very good and being an Interlock design should do very well at 9.3 velocities. Have you tried either of them yet?
Also, any of you guys tried the 250 gr Balistic Tip? I have ten of those to try, and am thinking of using them in my 9.3X57.
