Look into penetration results for whatever you can get your hands on. I would guess you want a heavy for caliber bullet and a truncated cone typically will deliver good energy and wound diameter with penetration. Buffalo Bore is well respected for hot ammo that works. I would be buying that 147 Hard cast and running a mag through the gun to make sure it functions and then pray that you don't need to use it. The +P+ Penetrator round would probably be a good option too.
