I think that you're on to a good thing, a good 160 grain bullet at about 3,000 fps from a 7mm Rem Mag is a deadly combination, and often quite accurate. The Accubond has a fine record of success! I've never used that particular Accubond, the 160 grain/7mm version, but from what I've seen of others, it should be good, real good.

Last fall I shot a fat 3x3 muley at about 150 yards, with a 160 grain Sierra SPBT Gameking, launched at about 3,050 fps. One shot kill.

I'd think that your 160 gr Accubond would do just as well or even better.
