If you are buying factory ammo I would give this a try. It is a 200 grain accubond and generates 3100 lbs/KE at the muzzle.

You seem to like the 165s and I have also used the Hornady light magnums (165 grain Interbond) on elk with good results. We killed 3 elk with them and had 3 pass thrus out of 5 shots. These rounds chrony 2950 fps out of a 22" barrel. Damage was tremendous, one of the reasons I am going heavy and slowing down is to limit damage.
