I guess I have to go with Loony on this one Cory. I don't really know if the XTP Mag will expand or not at the impact velocities you'll be getting, but if it won't I'd go with the softer bullet.

I put a hard cast 250 grain Lead Bullet TechnologiesWFN (Wide Flat Nose) .41 pistol bullet through the boiler room of a big doe. It penciled through. That nanny ran forever with that hole through both lungs. No, and I mean absolutely NO blood trail.
