I bet if your boys back that charge down to 90g, that the XTP's would work really well
You may also want to check out the Barnes bullets...I Know they are expensive, but they are a fail safe--that will always penetrate and expand

All my buddies that have used them, swear by them

They find a cheapo bullet that approximates the same ballistics for sight in, and finish off with the Barnes, so they are ready for the hunt!
