I ran some Nosler Accubond 160's through my 7x57 BRNO some years back. They shot reasonably well for a hunting bullet, but nothing special. I didn't use any on game. I ended up working up data with 165gr.(or 160gr.?) TSX at 2,700fps even. They were exceptionally accurate in that light rifle with that 'top' load by Brian Pierce - or was it John Barnsness - can't remember now? I do not have that data any longer however, as it went with the rifle to it's new owner.
