I don't know if I'd go with the PowerBelt either. To be honest, I've never used them, but I've heard that they can be a bit fragile too. They are designed to function at moderate velocity and some have said they blow up at high velocity resulting in shallow penetration. Again, not what you want with a 500+ pound animal. I'd look at the Barnes ML bullets. The Spitfire TMZ's would fit the bill nicely. You might also consider a conical lead bullet. The Hornady Great Plains conicals are great bullets. The 460gr flat point would do well I think. They don't go very fast, but they hit like a freight train. This bullet is responsible for one of my two bang-flops. I'd still lean toward the Barnes though. Whitetails are a dime a dozen, and just about any bullet will kill them if you hit them right. But I wouldn't trust a once-in-a-lifetime elk hunt to anything other than the best bullet I could find. I think that the Barnes bullets are just about as close to the perfect game bullet as one can get.
