Most folks out here shoot the 348 grain Powerbelt. The Aerotip, not the the hollowpoint. They seem to work pretty well on broadside rib shots. Testing I have done suggests they are a bit soft for encounters with big bone. I would also lean towards the 405 grain, or even the 444 grain.

In the past six months, I have been testing the new 338 gr. Platinum Powerbelts. They appear to be tougher than the 348 regular Powerbelt - maybe about the same level of penetration/expansion as the 405 gr. regular Powerbelt. They also can handle velocities approaching 2,000 fps while maintainting good accuracy. Haven't given them the wapati field test yet, but they look real good on paper.
